Some of the problems I have encounted.
Cannot install nVidia drivers. Loads of posts but no conclusive responses to get them working.
TV card installation. This not working. got the Nova-T searched loads of posts and nothing resolved to get it working.
Blue installing hardware boxes constantly popping up in top left corner.
Whilst playing movie / music volumn & search icons on screen not responsive. You select volumn button and the icons appear but you cannot control it correctly to select volumn up or down because they keep flashing and mouse keeps resetting to center of icons.
No music images for albums. Search everywhere nothing that solves problem.
OK here is just a few things and I know its early days for the software but I was using meedio before and ever though mce looks nicer it does not touch meedio for ease or use and installation.
MCE is horrid for browsing media something I hope the developers look into. Maybe look at meedio working on a well configured system to see how a nice user interface for a media solution should be.
Hardware installation is definatly something that should be looked into because there are a lot of people going to be put of by this. Ok I am not a complete computer guru but my 22 years as a games programmer and the time I spent writting software for microsoft taught me a bit about computers and even with my level I could not get the hardware ( as pointed out above ) installed.
Good luck with development guys and I hope you get there as so far it looks nice.
