Got my first ST in the second half of the nineties, and ended up in using the ST line quite a lot.
I have a 520 as well as a Milan Atari clone, and just now one of my Falcons is playing mp3 files.
My mainly used program on STs is Cubase, and on the 030+ machines I'm doing internet stuff mostly.
I rarely play games, but I enjoy Empire, Crown of Creation and some other a lot.
Atm waiting to give Epic a try, but well - no time for that.

Beside the Atari computers I use some more or less oldish Macs, a few PCs, some old Sun machines plus I have an Amiga 1200 standing in the tracks to be setup nicely.
Playing with UNIX on the Suns is quite hard when you are a UNIX noob like I am.

All those older machines are fascinating, but I like my first Falcon most, and I use it more often than my considerably faster second Falcon.
