Hi, for a long time I've wanted to learn how to write software for the Mac. I've gotten Aaron's book (a couple times) and worked part way through it but ended up flaking out and stopping each time. Well, now I want to do it again. I was wondering, though, would it be better to learn Mac programming or iPhone/iPod programming? How similar are they? I don't have a special goal in mind, I just kind of want to learn it and see where it takes me. Is one more accessible than the other? The only thing I can think of that would weigh in iOS' favor is that iOS apps are usually smaller scale and single-purpose, while a Mac application is usually a larger endeavor. With that in mind, maybe learning iOS would be more rewarding. What do you guys think?
