I'm getting more and more interested in Android -- especially as the newly redesigned XCode 4 is the worst IDE I've ever used -- but I am not going to read a review by someone who finds Obj-C a significant effort to learn from Java. That's a sign that you're a code monkey and not someone who has anything close to a deep understanding of programming; moving in either direction between Java and Obj-C is one of the dead-simplest transitions amongst distinct programming languages.
The concepts are virtually the same -- ok, exactly the same -- but the syntax of Objective-C, namely "message passing", took me some getting used to.
