My first Amiga was (and still is - I still own it) an A500 bought in February 1990. Beforehand I'd had a Spectrum 128k +2, and the jump to Amiga was nothing short of astonishing. Within a year, the A500 had an A501 RAM expansion, twin external floppy drives, a Mastersound sampler and a Phillips CM1183 Monitor.
I can never forget playing stuff like Batman the Movie, Interceptor and Shadow of the Beast and thinking "wow!".
Since then I bought an A1200 in January 1994 (which I'm using right now) which has been upgraded over the years ;-)
Elsewhere I have a PS2 and an Athlon 2500 PC.
