Deleting files and the GUI complaining that it's still in use has always been a frustrating thing. Why hasn't anyone at least taken the next step of showing what the user can do to delete the files? I've always resorted to opening Terminal and using some sudo's and some -f's. In regards to his question about future OSes, anyone think about a browser/cloud based OS like ChromeOS or JoliCloud being able to save him? These are the future of OSes so it would seem natural to look to them to create that simpleness he's complaining about.
