The first computer I used was probably an Apple IIe. Our elementary school had a computer lab with about twenty of these, only two of them had color screens. I remember there would be some fights over them.
The first computer I owned...well the family owned was an 286 I think. I was quite young at the time. I'm not sure if these specs were all from the time, as it got upgraded a lot: 100MB hard drive, 4MB RAM, no sound card, 16 color graphics.
Time passes, now I own a computer I built myself and a laptop. Desktop is a 3200+AMD 32bit, 1280MB RAM, about .5TB (~500GB) hard disk space, ATI 9600XT AIW. Laptop is a 2.0GHz Centrino with 1024MB RAM, 60GB hard drive, ATI x300.
