I haven’t updated either my iPhone or iPad to iOS 5 yet, but, as a programmer, I’m happy to see that they’re finally doing automatic reference counting in Objective-C. I’m wondering if the instructor for my NYU iOS class is going to work any iOS 5 stuff into the class or not. I could see where it would be hard to update class materials on the fly for this stuff, and our classroom iMacs probably still haven’t been updated to the latest version of XCode, but I’m hopeful.
