I have a minimig and it's a great little Amiga! I know I haven't pushed it to its limits, but for showing off demos and playing non-AGA games it's perfect.
It's also the most portable Amiga. Heck, you can take it to a friend's house with a couple of joysticks, and use their keyboard, mouse and monitor to play games.
Minimig is a nice addition to my retro hardware and I'm not worried about it blowing a cap and failing any time soon!
