Their computers are pieces of unupgradeable crap.
You obviously have no idea what you're talking about...
Maybe the iMacs aren't easily upgradeable, but what idiot would buy one of those thinking they WERE easily upgradeable? Stick with the towers (Mac Pro, G3, G4, and G5 towers), they might cost more upfront, but they last forever! I'm still using a G4 tower from 2001; Dual 1GHz G4, 2GB RAM, and an updated graphics card and HD. Has worked flawlessly since day one.
If you are into playing games, then look elsewhere. But if you use your computer for audio editing, video production, photo editing, or anything else that requires a lot of "guts," then why waste your time with a PC?

And BTW, I too have this stupid January update problem, but as was mentioned earlier, just clicking the "x" before it loads works fine...though I would like to see this remedied in the near future.
But in reality I don't think we should expect everything to work flawlessly when we're running JB'ed touchs. And I still don't understand why so many people are still whining about the $20 for the extra apps. It's not like anyone is forcing you to buy it, so what's the big deal? Jail Break that b*tch, and move on. Of course I also have no idea why so many people are affraid or just morally opposed to Jail Breaking, seems stupid especially since you can always restore if you don't like it.
