I'm really looking forward to Snow Leopard, there have been more than enough really cool new features added, and I still haven't really explored all of them. All of the applications have come a long way since I first started using OSX, right before the time when Apple officially announced the transition away from OS9. Some of the new applications aren't quite as polished as they could be, and OSX has grown significantly. Hopefully Snow Leopard addresses all of those issues and increases the performance, security, and reliability of the OS before focusing on new projects. It's always easier to build upon a strong base, and it helps locate potential problems along the way.
