Heh, I remember getting my desktop machine in 2003 after graduating High School and thinking "Wow 512 MB RAM, I'll never need more than that"
Kind of accurate, that computer ran everything I had at the time perfectly including a few games that I had never gotten to work right on my older computer.
I don't think I got a DVD writer until 2008. I had this really cool media machine with a TV Tuner, lightscribe (etching software HP made that used laser to label a CD) and 2x250 GB HDD mainly for DVRing stuff. Media remote too. I need to build another media machine with a TV tuner I think. Now that everything is wireless though, it just doesn't seem as cool.
