Keeping things the way they are, while not good for me personally, I think is a good move for Apple. Cocoa is so compelling that it a real reason to make mac-only software.

The problem with this is that sometimes that just isn't an option. Just imagine it... one project, windows, linux, mac, and all using the best API available. I know that there are some interesting projects going on, gnustep for example... but its just not the same.

hey, cocoa's roots were cross-platform, so why not :)
