Hot on the heels of the McIntosh product placement in Elementary
(could have got some better speakers though), did you spot the Vita Audio R2i in the second episode of Sherlock?
I've actually got an it's bigger brother, an R4i, and use an ipod Touch as below.
Really nice sound, for such a small box. I do, however, find the remote a little quirky, and it uses AAAA batteries - not something one can get from the corner shop.
For those with even bigger ears there's now the R7 - legs detachable, if so required.
