PC vs. Mac.....get ready for the flame wars...!!...:laugh:
All computer hardware can and will fail. There are viruses and spyware for Macs....don't kid yourserf. Which one is better? Honestly, I think it's a coin toss. We have PC's because I build my own, and think the value for the dollar is far better with PC's.
W7-x64 on my machine at home and on my monster computer at work, W7-x32 on the wife's machine, and XP (still) on my corporate laptop. Our computers are fast, rock solid, completely stable, and great to work on. I just don't buy the "Macs are so much more reliable than PC's" statements becasue I prove that wrong every day. However, I know how to maintain my machines, and don't crap up my machines with every downloadable spyware and spamware application under the sun. Worked on a guy's machine that had 30 or so of these "toolbars" running in the background.....he couldn't believe how much faster and more reliable his computer was once I deleted all the crapware.
I think either platform can be fine, and really, at the end of the day it's all about personal preference, and understanding the tool so that you can maintain it properly. PC or Mac, they will need some maintanence at some point.
If I were in the market, I'd pick up a Lenovo laptop and W7-x64...and I'd be very happy with the choice.

this or maybe
