Re: iPad Application Development
Objective C, Cocoa and the Apple tool chain are not that straightforward, and you will find that by the time the new one comes out the differences should help you understand it better.
That is assuming you are working on the approved Apple Tool Chain. I. E. With a Mac. I will occasionally look at/use GNUStep which is part of the alternative for Linux/Unix stuff. I come into contact with people who are trying to use it for the iPhone/iPad/iPod touch and have come to the conclusion that if you don't want to use the approved toolchain -- for that -- don't even bother. The other uses are pretty good, but we have been messing with GNUstep since about 1990. Apple does want to lock you in to their tools but the alternatives are really not good for it.
