The EVE client on Mac is better now than when it arrived. For me, it was utterly unplayable in the beginning, with like 12fps and major graphics issues. It's since improved though.

It's never my first choice, but to be able to log in quick for a convo, check my evemail, switch skills, it's great to not have to boot into XP every time. If I'm really going to play, I'll play with the PC client.

Obviously the Mac client doesn't support Premium/Trinity graphics, and that dev blog on this is now some months overdue, but I'm still glad they offered it. Were I to rely on this for my actual play time in EVE, I'd be a bit disappointed. But for what I use it for, can't complain really.
