I've also just been evaluating Wine on Mac OS X - and in fact last week downloaded the very nice WineSkin and WineBottler incarnations. No real complaints yet :) Actually there is one thing I haven't got figured out yet - not sure if it is meant to work or still a bug on Mac. That is, I want to open URLs in the host browser (ie Safari on the Mac OS). I've tried a number of things but don't seem to be able to get it working. Otherwise, good work on those two Mac 'packagers'! And of course CrossOver!
