My parents are pretty computer illiterate anyway so I'll just add shortcuts to the programs they use ( email, firefox, etc. ) on the desktop and they're set^ ^  
Right now I don't specifically use any any programs to speak up besides,
 msn messenger, picasa ( google photo thing), firefox, limewire when my sister comes home...:\, spybot search and destroy, AVG, etc..   nothing that I'v really bought besides some games.
I currently don't have a game that even requires better than an old P4 so this computer will be an eye opener for games.... 
FYI.    I have a HP running at 789MHz, 300RAM, integrated graphics...xp home.    Web browsing is a pain lol.
