Mine's excellent. The iWork and iLife packages work fantastically, as does MS Office (if you're that way inclined!). I've used some pro apps too, but clearly they're not so fast as a dual G5 PowerMac or something.

Most limiting factor for me is RAM. I got 512Mb, and Activity Monitor shows a maximum of 33% free at any time. I've got Firefox, Pages, iTunes and Adium going at the moment, and the RAM is just about maxed out. A good chunk is 'inactive', though, so we haven't ground to a halt yet.

I've only moved my mini a few times, but it's handled the journey really well. It integrated into my work network when I took it in a couple of times (only to show off, I must admit!), and it survived a house (and ISP) move with no difficulties. It is deceptively heavy though - remember all those components densely packed into the little box!

I've had mine over a year, pretty much since they launched, and I'm really impressed. It's only ever crashed (completely frozen and become unresponsive) twice at the absolute most in that time, and that's probably because I've being trying to install some open source stuff and struggling with dependencies and other vaguaries. I've also reinstalled the OS once, but only to upgrade to Tiger! Compare those stats to any Windows machine....
