Some IBM-compatible Commodore 286 with 640KB of RAM (but MS-DOS used about 128KB of that, so I only had 512KB for games), 4-color CGA graphics, and two 5.25" disk drives. I loved the chunky feeling of inserting those gigantic floppy disks and clicking the lock into place. Computers were so much more tactile back in the day.

Learned GW-BASIC on that thing when I was like 5 or 6. Good times.
Next machine was an IBM 386 Windows 3.1 box with something like 2MB RAM and a 20MB hard drive? I forget. Upgraded to QBASIC on that thing. <3 SCREEN 7 <3
Then in like '97 we got a sweet super-gimmicky 200MHz Windows 95 machine. It was an IBM Aptiva S (my parents had a thing for IBM back then) that came out during the heyday of gimmicky PC designs. It had a wireless three-button mouse (no wheel, though); the speakers were integrated into the monitor (ha, remember that?), and the monitor sat on top of this little external disc drive thing. I basically never touched the actual desktop box. It sat on the floor and collected dust.

Oh yeah and it also came with a flight stick and a folder full of games discs (some demos, but mostly full games).
Sooooo gimmicky in retrospect, but I thought it was the coolest thing ever when I was 13.
I guess I've had about four machines since then, but they've all been fairly uninteresting. My most recent one was also the first one I built myself (got it back in June '08), and I'm going to build another one next weekend.
