Starke:
My main real Amiga is the A2000. Nothing special, just a 2000 with a GVP 030 combo, 2091, and a Toaster. It's mostly retired now too. Most of the time I use UAE on my crappy PC. It's got a copy of the hard drive from my 2000, so it's almost like running my 2000. Except that "start toaster" icon doesn't do anything. ;-)
As for OS4 and beyond, I'm in a wait & see mode. If reasonable hardware shows up, I'll look at it. I'm not going to buy into it, just for the sake of having an Amiga. Actually, I'm almost more interested in the Minimig.

Oh yeah, I use a PIII machine salvaged from the trash. It runs Win98SE.
