No surprise from Roku there - people who listed to 'media' via white earphones are hardly your typical purchaser of a standalone radio set. And yet most Internet Radios I've come across would bamboozle your typical over-50's user on first acquaintance, so why would they buy it?
Sure, the extra stuff that IR can do which traditional FM can't, maybe I could accept that might take a little getting used to. But for the basics they should be no more complicated than an ordinary FM radio. That way anybody can get to grips with it as a radio without feeling like an idiot. But I know that if my Dad is asking me how to get Radio 4 on the device then it is really a non-starter in terms of mass market success.
I think the acid test would be this - if Radio-Jo/e average can't just take the thing out of it's box and have it playing what they normally listed to on the radio, inside 1 minute, without phoning a friend, then back to the drawing board. Complex does not have to be complicated.
