To me instability across the board on CS6 in the current build is still not at all ready for deadline work. Maybe if I were Adobe I would have waited a bit before release because to me it's at the level of near-release beta software, not something I would feel is ready to sell as a professional tool.
CS5.5 was/is AWESOME. CS6 crashes once an hour or more, and I really can't deal with that level of headache.
We are working on several Mac Pro towers.
Is the PC release more stable?
