i do not believe powerpoint or any m$ program files will be accessible through skinny. from what i understand it is for simple, low power apps made with a web programming protocol. and having the app approved by sony is no different than apple approving all the apps on their store. this is done to make sure that no "questionable" content is released and that the apps will not harm any system due to malicious programming or that the programmers will not put in any code to steal psn ids and passwords. i approve of sony approving apps. i just hope that it is actually feasible for users to generate their own apps to release.
