Zoutube and mtube is in the Extra-testing or Devel repos.
Car racing game is not yet written, but you can use SNES to play most games anyway.

FYI, this is Linux, Linux is not all about graphic layout or pretty graphic UI. Linux is an Open source OS. So if you think the apps are out dated then why don't you contribute and make it better from the source code

Please be patient and wait for PR1.2 update. This will make more eye candy apps coming along the path as well. The games are also coming to the N900, as you have a ready know that the OS is only a few months old. So there are still very much needing a lot of works and apps are written by people who has spare time to contribute into the project.

So please do appreciating their time and efforts. Without the people like them, there will be no apps or worst no more community to help you out.
