I'm thinking about getting RMBP or Mini+Air. I would use it for programming, both web and iOS/Mac applications. My current 2009 MacBook Pro was a fantastic machine until Xcode4 happened. --- If I get RMBP, I'm afraid it will break and I will be without a Mac, which is for me like walking on a street naked. Also it's very expensive. But it's powerful. If I get two computers, they will be both not very powerful, and I don't think they'll last for very long. On the other hand, it would be cheaper to buy a Mac Mini now, and still use the Pro as portable computer, then maybe someday replace it with an Air. --- Also, I would use it mostly at home office, 2-3 times a week in school, and maybe 1/3 of year traveling. --- Anybody has been in the same place? Any advice? Thanks!
