I've been reading a lot of mixed reviews of the 3.0 beta on here. Some say it's good and stable, others say it's awful. How is it, really? I'm thinking of buying the $100 Developer account for 2 reasons: 1, because I would like to get into coding with Objective-C and the iPhone seems like a good place to start and possible make some money, and 2, because it would be nice to try out 3.0. Obviously reason number 1 is the main reason; 2 is just a benefit. But I want to know, how's the beta?
