As much as I enjoy my current HTPC setup, which is a laptop connected to my receiver set in projector only mode (aka just 2nd screen) running XBMC, I'm finding I'd like a more compact and flexible setup.
The reason for this is I absolutely HATE XBMC's music player/setup, as well as the fact I'd love to be able to access Youtube, or other streaming applications without having to well go to the laptop itself, open the application and navigate. I'd rather be able to control the device with my phone/remote and just easily swap between apps.
This is why I'm thinking about going towards an AIO solution instead, such as the Pivos DS Media Player, the Ouya, etc. I quite like the idea of having an small android device where I can easily control/swap between xbmc, a better/wide assortment of music players, youtube, Netflick, etc.
Now I'm not sure what would be the best device to go with, but I know after spending years on XBMC on an htpc/computer I'd like to try something different (I did enjoy the first gen Pivos AIOS, though it was lacking some features which resulted in me returning to xbmc on an htpc).
