I am using Ubuntu One Clients on different platforms and it's all working very well, as there are Win 7 PCs and ubuntu 11.10, where it is integated already. Now i'm trying to add my mobile, which i thought would not be a problem, as my mobile, a nokia N9, runs on MeeGo, linux in fact. Could there be a chance to get a client for MeeGo? Android and iOS are existing, so could it be a hard challenge? I also thougt about switching to dropbox, because clients for Windows, Ubuntu and MeeGo are available at dropbox, but as a linux-fan i would of course wait for a ubuntu One-Solution. all i could find was a project at google, you can find here: http://code.google.com/p/meego-u1/ unfortunately i am ony a user not a developer.
