I hope there isn't another thread about this same topic. I looked and couldn't find one. I have a new MacBook Air with Mountain Lion. If I install the beta, and I'm tolerant of some bugs, will I still be able to do most everything I can do now? I want to download Xcode 5 and start learning to develop (with the latest tools) for iOS. I don't depend on this new laptop for work/school but I have been using it with AirPlay to my Apple TV. Will that still work do you think? AS a beta I don't expect everything to be finished and bug free of course. Thanks for your opinions.
