Its fine Cellar.. So far have not heard the multimedia gurus come on line here..
I think navigation features are a big plus in any music player.. and one should should have the mix and match which is anyways available on a HTPC or a laptop.. HTPCs are good.. not a doubt.. the issue is in sittiing on a sofa and steering out at a screen 15+ feet away with a huge keyboard like device. I think we should have something more handy..a remote qwerty keypad combi.. like the boxee. unfortunately the boxee does not have a hdd bay and its again welcome to the clutter. I would prefer something more compact and neat with all the features one would look in mm device - navigation, mutiformat play, HD upscaling, future proof-upgrade for compatibility with new formats, flac play, usb 3.0, + 2 , Mutiple filesystem operability, speed (a good processing) with no lag, etc.etc
