Uhhhhh, you guys all know way too much about computers but I'll take a shot:
I have a COMPAQ, it's about two years old. I dunno how much RAM it has (1 gig, does that make sense?). The hard drive is 90 gig and it has an Althon micro processor but I don't know how fast it is (does 1 Meg sound about right?) It's got the DVD & CD/CDR deals.
I also have an HP laptop which is a little less than a year old. 40 gig hard drive and an old HP Pavillion from 1998 (this is an OLD machine, still runs windows '98) in the basement networked to the others. That one is a 400 mHz speed pentium with not a whole lot of RAM. I think it has a 12 gig hard drive.
I had a Dell from 1998 or so. THREE hard drives failed so I stay away from Dell. Right now, I installed the third failed hard drive in my Compaq so I'd be able to access all the data files I had on that drive. This hard drive has failed so badly, everytime I boot up the Compaq, it tries to run a disk check that can never be completed. Again, why on earth these guys can't use decent hard drives is beyond me so screw 'em, I go with Compaq/HP
I'm not a MAC fan.
