The thing I liked about the Amiga (and to some extent, consoles) was the fixed, but exploitable hardware, encouraging artists/programmers to improve their skills, rather just expecting users to upgrade.
constant need to upgrade is why I stopped playing PC games. now consoles are dictating the pace, i find myself using the PC a bit more for games.
saying that though, the A1200 spec was to low at lauch to stick with for 5 years.
