This is my desktop PC, according to my "system properties"
Intel Pentium 4 1600 MHz, 1.50 GHz, 512 MB of RAM, Windows XP 2002
I barely know what that shit means, but it has run flawless for the past 8 years. I have never had to replace or upgrade anything, and it isn't slow, despite having several programs, games, and thousands of mp3 files. Not including the monitor, I think I have about $100 invested into the entire build of the computer (it was 8 years ago so I can't remember exactly).
All the Macs I have used in the past were annoying hunks of garbage, but to be fair, I haven't had a significant amount of exposure to one for several years. From what I've seen their newer laptops are ok, but I can't understand why anyone would pay $3k for a MacBook Pro. Does the thing suck you off while you're using it? It's a fucking computer; why anyone would spend that much is beyond me.
