I'm actually glad the select button drills down. They should however make sure there's a long-press option to start playing on it.

Of course I'd prefer if the method to drill down involved pressing a button to the right. The mechanical scroll wheel precludes buttons within the scroll area though.

With their layout the first thing to improve the unit would have been to swap the Home and "+" buttons. Their positions are completely illogical right now.

They also need a sot of quick-menu that can be invoked while on th enow playing display. It would pop up a few option for relevant commands, such as Shuffle Toggle and Repeat Toggle. DId you catch how awkward it was to find Shuffle in the video?

The good thing here is that all this stuff can be changed. It isn't horribly set up and forever doomed to be crap like the iPod UI.
