I just decided to learn to program native OS X applications, and when I learned that Objective-C had no garbage collection I was disappointed and a little shocked. I've never had to manage memory in APIs I've used in the past, and I certainly wasn't looking forward to it. When I found out that garbage collection might be coming in OS X 10.5, I was excited about programming for Macs again. For me, G.C. is a goood thing.
