PC Duster Gas

But seriously.
Buying one
Base level MiniMac: $500
Base Level OEM PC: $300 (includes moniter)
Upgrading one
Mac: Throw it out, buy a new one.
PC: Go to Newegg.com and pick out your parts. Many regular stores sell them too.
Setting one up.
Mac: Plug it in. Press power, wate 10~20 minutes, start actual software setup. Plug in all your printers digital camera's etc, find out that there isn't a driver for your new Motorola L7 (iTunes phone). Bitch the computer out for not having your driver, and bitch out the modding community for not giving a flying f*** about macs
PC: Plug it in, press power, wate 1~5 minutes. Start software setup. Install all drivers. Thank god that the third party loves and works on PCs as you mod your L7 to be really cool.
Viruses:
Mac: None, but then again who wants to screw up a Mac any more than it already is?
PC: about 200,000 a year, however if you have even the slightest bit of knowladge, you know how clean your computer.
Software:
Mac: iLife, iGurd, iTunes, basically if it starts with "i" which is about 10 pieces of software. Oh ya and then everything Adobe makes.
PC: I lost count at about 999,999,999,999 and thats only the payware, there are billions of freeware apps.
Useing it:
Mac: Its like being on a limited user account, but you can install new software. Also its widget heven.
PC: I <3 Microsoft.
Crashing
Mac: Try deleting something. System locks up, unplug, reboot. 30 Minutes later after trying to open IE it happens again.
PC: Run too many apps, and it happens. Ctrl+Alt+Del ususally fixes everything. You can also try Alt+Tab. Still no luck reboot. And anyone with the blue screen of death just dosn't know how to use a PC.
I would say thats about as clear as it gets.
Cheers
