I just switched. Like, a week ago.
1. Expose + Spaces are GREAT window managers. I took to both like ducks to water.
2. Spotlight is pretty awesome and intuitive. However, Win 7 has features like that integrated.
3. I never used the Explorer, always just navigated through folders one by one (bad habit, I guess). So Finder has been a bit of a learning curve especially since the opening folders behavior is not quite the same. Like when you double click on a new folder a new window opens up.
4. No registry is great. Installing/uninstalling apps is clean and efficient. Just the way it should be.
5. The Dock is a mess. Of course, this is nothing new. Many, many people have spent tons of time talking about it. However, it is fairly intuitive and simple to use. It's also very tweakable for those who want to do it. I guess that's why Apple has kept it around.
6. I like how Mac OS X keeps all the power user features out there and accessible. Automator for example. OS X looks nice and is easy to use but is actually extremely flexible and powerful. Windows, of course, you can do a lot to tweak it, but it just doesn't feel the same.
7. Quicktime-stuff and iTunes run MUCH better on the Mac. No surprise there.

While I am not a nuclear engineer, I do have a fair amount of knowledge in the area, so with that in mind I can personally say that this will NOT become another Chernobyl situation. Again though as a disclaimer, this is not my career.
With that said, the BWR should be fine. What we saw earlier was the steam blowing apart the structure-- this just means that they didn't do their job in relieving the pressure. The core should be intact, and the reports state that the housing is still in place. When the control rods are inserted into the core, the rods will not melt down, however heat WILL still be produced. In this case, steam. Steam voids moderate fewer neutrons, causing the power level inside the reactor to lower. Furthermore, there should be safety overpressure valves... not sure why these didn't work; they may not be there due to the age of the plant.
To quote wikipedia about BWR safety:
Because of this effect in BWRs, operating components and safety systems are designed to ensure that no credible scenario can cause a pressure and power increase that exceeds the systems' capability to quickly shutdown the reactor before damage to the fuel or to components containing the reactor coolant can occur. In the limiting case of an ATWS (Anticipated Transient Without Scram) derangement, high neutron power levels (~ 200%) can occur for less than a second, after which actuation of SRVs will cause the pressure to rapidly drop off. Neutronic power will fall to far below nominal power (the range of 30% with the cessation of circulation, and thus, void clearance) even before ARI or SLCS actuation occurs. Thermal power will be barely affected.
In the event of a contingency that disables all of the safety systems, each reactor is surrounded by a containment building consisting of 1.2–2.4 m (4–8 ft) of steel-reinforced, pre-stressed concrete designed to seal off the reactor from the environment.
Again; BWR =/= graphite moderated reactor. Why does no one get this?! Everyone will be fine.
Two more bones of contention (which will give you my perspective):
-I personally believe the linear no threshold model is crap, even with the adjustment factor
-I also personally advocate the use of thorium... there's many benefits, melt-down control being one of them (because of MSR)... also although there's still fabrication issues, thorium can be used in existing LWRs. There is also proposed designs where the thorium has to actively be fed into the core, providing a great shutoff mechanism. The only con to this is the fact that thorium is more radioactive than uranium, so it's potentially more dangerous. I think the pros outweigh the cons.
Do you have a link for this? I'd like to read about it. I would think a system setup to automatically scram when power is lost would be the ideal.
Sure! It's really rather cool. (No pun intended)
For starters here (http://en.wikipedia.org/wiki/Boiling_Water_Reactor_Safety_Systems) is the current safety systems that are supposed to be in all BWR, however since this one is from the 80's, it's really hit or miss-- I can't answer that.
New reactor designs have these systems in place-- for example the Westinghouse AP 1000's. (here (http://www.ap1000.westinghousenuclear.com/ap1000_safety_psrs.html))
A general link about passive safety here (http://en.wikipedia.org/wiki/Passive_nuclear_safety).
Basically though, the idea is that human intervention, mechanical or otherwise, is always the weak point in nuclear safety. Instead of relying upon mechanical or man-controlled means, these safety measures employ the laws of physics and thermodynamics, which I hope are always working :D. Many of these systems rely on heat sensitive plugs connected to tanks to flood the chamber or coolant systems via gravity.

Faster at what? I'm too lazy to find the part in the keynote where they showed this. Was it 20% faster at something designed to use all 8 cores?
The task was a multi-threaded matrix multiplication that easily scales to multiple cores.
This is representative of many HPC and rendering apps, but not as realistic for most desktop apps (unless, of course, you're like MultiMedia and run several separate instances of the desktop apps simulataneously).
The sections in the video are at 11:50 to 15:00, and 26:30 to 28:00. (The gap is while the engineer is swapping CPUs and rebooting.)
My earlier numbers were a bit off - rewatching the video the Woodie system was 40% faster than the Opteron, at 17% less power. The Clovertowns were low-voltage parts "about 900MHz" slower than the Woodies. The octo (dual quads) was about 60% faster than the Opteron at 17% less power. (I'd like to have seen them put in faster Clovertowns, and show what the octo Clovertown would do when matching the power draw of the Opteron.)
At about 25:00 minutes in, Gelsinger says that the "two woodies in one socket" is the "right way to do quad-core at 65nm", due to manufacturing and yield issues.

"We grabbed a pair of 2.4GHz Clovertown samples and tossed them in the system, and to our pleasure, they worked just fine. Our samples used a 1066MHz FSB, although we're expecting the final chip to use a 1333MHz FSB, but the most important part of the test is that all 8 cores were detected and functional. "

Theres also a lovely massive gaping hole in the Catholic "Invisible God who must exist because 1st Century Nomads who couldn't work out keeping toilet and food separate was a smart idea said he did" view of things:
Assume God Exists and isn't okay with homosexuality:
God thus made Humankind. => He invented the way we think => He invented the concept of sexuality (So we could reproduce) => He invented homosexuality as an option within sexuality (Since he invented the concept, he had infinite control over it, thus he could develop it however he wants, including only having men like women etc, as seen in many animal species, which he created under this model, so he must've known he possessed the power to do so) => He must be okay with it, otherwise he wouldn't have come up with homosexuality in the first place. ergo your god either likes homosexuality or doesn't exist. Quite evidently I believe the latter.

I'm wondering why they couldn't/wouldn't just combine the mini and the iTV into a single unit. The mini's size could allow for a DVD slot/player/burner and maybe even allow for the Mac OS in the box, so you don't need another computer to stream your media from. In fact, I assumed that was what the Mini was ultimately destined for anyway.
Thoughts?
What do you thnk the iTV offers that a Mini doesn't? I'm not sure it offers anything other than freeing the Mini so it can be used as a computer in front of a computer monitor somewhere else (which is apparently Jobs' view of where a computer should be).
I might have the wrong end of the stick though.

Each process is it's own thread. And most processes have multiple threads. Unless you only always have one program open at a time, more cores always can help speed up your system.
Open and doing something. Safari, Mail, iTunes, and working in photoshop probably won't benefit much from quad cores. Batching in PS, Aperture and doing a render in FCP would.
I am on the brink of buying something. What, time will tell. If the quad core does make a marked difference when running PS and at most one background process I'll consider it. Otherwise its a Dual core 2.66 for me.

But just like Windows, it's practically impossible to have any problems unless you do something stupid.
Another analogy - if you buy a car and put the wrong type of oil in it or inflate the tyres to the wrong pressure, bad things will probably happen.
If you don't know what you're doing with your own devices then maybe you need Apple to hold your hand.
Well, there are a few problems with your theories. First of all, there are vulnerabilities in Windows that merely visiting a web page clicked on from a Google search gets your machine infected. Or, you could visit a legitimate website that has mistakenly sold ad space to people hosting malware (this has occurred with both Foxnews.com and NYTimes.com), or you can download an app that you think is legitimate, but has spyware (like PrimoPDF).
I love seeing this "As long as you know what you're doing, and you're not an idiot, you're fine" attitude.

If I have a mini, couldn't I use it as an iTV with frontrow? Why would I get an iTV when I can get a refirb mini for $200 more, when it can do more?
Because that ties the computer to your TV (see my post about teetering keyboards above). This way you can have the computer and still display stuff conveniently on the TV, wirelessly.

Yes, but EyeHome does not support ALAC or Purchased AAC for audio, H.264 for video, it does not have a USB port to connect a USB drive with movies or music or to use it as a file server with that drive or hook a USB printer to use it as a print server. Needless to say, it cannot access iTunes store content, either. If iTV can do all of these, then it is definitely gonna be the winner.
All true... I still don't think that it's anything to jump up and down about.
One sad side-effect of the iTV however will probably to kill off any other 3rd party streaming boxes (either out today or in the pipeline). Elgato already has practically burried the EyeHome on their site... :-(

To be honest, I'm not too upset by this. I've used an iPhone for tethering via jailbreak long before the official support came. I did that fully knowing that I was breaking the rules, and that ATT might mess with me, but they didn't offer an official plan so I knew the risks. I still jailbreak my phone and use MyWi, but I pay for an official tethering plan so I'm not breaking the rules.

The trouble with DRM is that it often affects the average Joe consumer more than it hurts those it's intended to stop.Yep. This is true of many laws.
DRM embedded in iTunes annoy Joe Public who burned a track onto his wedding video and now can't distribute it to the wedding guests without working out an authorise/deauthorise schedule.Actually, they get even crazier when you start making derivative works like that. I do video as a hobby and have to be very careful if someone asks me to put a commercial track on the wedding video I'm editting. Technically, I cannot do it without a syncronization license plus royalty payment agreements for each copy sold. Just try to pin down a videographer on the legality of this - it's a HUGE grey area in the fair use clause. Some artists and/or labels (so I've read) won't even let you do it if you are willing to pay for said licenses because they don't want their "art" mixed with someone elses (the video).
The record companies assume everyone is out to be a criminal while the 'criminals' don't bother buying DRMed files or strip out protection and do what they want so just as many files end up on P2P networks and on dodgy CDs on street corners.Welcome to humanity, were the one jerk always screws it up for the rest of us. :mad:
