Yes, just bought one a month ago. Great performance, wonderfully quiet, excellent form factor.
I used to be one of those angry people complaining about no midtower. I'm not a gamer, so the video is not a problem. The mini is really very underestimated. For example, I encoded a one hour video and burned to a DVD in one hour, very acceptable (especially compared to my dual 1ghz QS). Avoiding the iMac as I have several LCDs, and just can't deal with the glossy screen.
I bought the 1.83 and upgraded the combo drive with a Pioneer superdrive, works excellent. So, I'm hoping a bump in specs tomorrow and if so, I'll be buying two, and replacing my QS and a PC (and just use Fusion for XP stuff). Down the road, the cpu is upgradeable as is the hard drive, so I'm happy this will be a long term purchase.
