Well, it works, and it's fantastic. I have it playing a concert via 6 music iPlayer, it's bloody impressive. It plays YouTube clips, albeit the recording quality on most of them is poor. I couldn't get it running on an Amazon Fire tablet, which one would have thought it would, so that's one for later. I can't get my music library, via iTunes or WMP, playing, either.
I think it's at its best on a dedicated device, I currently have it running from the lappy and if I'm doing stuff on the net at the same time it coughs and starts a bit.
It's destined for a kitchen system, if I can get it playing my music as well as the online stuff, it will be a 100% fantastic review. If it only does the online bit, fantastic, but I can do this via a £30 Fire tablet. For £20 though, wow.
