Hi!
I like the Cube H100HD very much. It plays all the formats I need (mainly H.264/AAC in MP4 container) flawless...
The screen has good colors.
Though there are some bads:
My screen is somehow smeared from the inside

Looks like they did not clean the Plexiglas before assembling the device...
The UI should be reworked for the Cube. It feels always strange to operate with the semi-scrollwheel AND the buttons...
This is because the UI works vertically (scrollwheel) and horizontally (buttons) (This works better on the Ainol HDV/HDS which has only buttons).
It should just work vertically, so that you can always use the scrollwheel...
It's a nice player if you can live with that!
@Raz: Yes, we need a Cube forum!!!
