Why hasn't anyone thought of creating a more media-centric hub for use on our PS3? They have such things as LinuxMCE (www.linuxmce.com) which is notably better than Windows Media Center, and installs on top of Ubuntu. We already have Ubuntu working (sort of) on the PS3, so why not port this over to the PPC platform to use it?
Better yet, why not start from scratch? Why not create an entire OS based solely on LinuxMCE?
Instead of a generally useless Linux OS that resembles a slow, dumbed-down, and more complicated version of our 'real' computers, you'll boot to a simple media center menu automatically connected to content on the PS3, as well as media shared over the network from our other computers. Of course it would have the usual internet browser, as well as other general computer-like features, but still be completely usable for the computer-illiterate (well, nothings that easy).
I personally feel that creation of such an OS for the PS3 will have a much better impact on users, as well as give the PS3 the edge we know it can have, and needs.
Obviously it's not an easy task at all (thanks Linux). After reading a little from www.linuxfromscratch.org, I gave up...but I know there are people out there with the knowledge to put something strong together. With enough knowledgeable people on the project, I really think it could be a success, and the bragging-rights of the PS3 'homebrew' community.
