If there's C2 on the Mac I would drop my windows laptop in a beat :P
Mainly because I'm also doing iOS development at the same time so having just to use one laptop for everything would be awesome.
Unfortunately I don't have enough space on my macbook to install windows 7 bootcamp so that's out of the question.
All things aside, I would prefer the team to focus on making C2 even more awesome on one platform rather than going multi-platform with mediocre results :)
