Why are you asking? Preference is a very subjective thing, so what does it matter if 100% of those who reply say PC but you want a Mac, or vice-versa? What's your take on the Lenovo ThinkPad you used to post this silly question with? How is Windows 7 working out for you? DDR3 in a laptop, must be new... ?
If you have no idea how to operate and maintain a PC then for that person a MAC would be better. As for the person who knows how to maintain a PC the proper way, then by all means a PC rules in price and performance upgrades as well as customization.
Cooler Master CM690 II and Hyper 212 plus / I5 750 @3.6 Ghz / MSI P55-GD85 / 1TB Caviar Black / 4GB Corsair XMS3 1600 / XFX 5850
I own both and use each for different things. PC for Media Center Server for Xbox 360
and also lots of PC gaming. I own the Mac for travel and Internet. I'm on my macbook doing schoolwork, research or anything that doesn't require sophisticated function. I utilize my IBM for network engineering and Linux testing. Those who know most will always tell you to use the right tool for the job and don't be a blind hater on either camp. I prefer PC but i like to use my Mac too.
