nokia n900 can do everything but I think we need a video player that could easily play HD stuff, that's it . something like vlc.
i want "Splashtop Personal" to be ported to Maemo, they even have the source code available on there site for 32 & 64 bit x86 arch. http://www.splashtop.com/linux if we get it, its gonna be a killer app.
