above is the korg nanoseries; 3 usb devices to attach to the computer for use by musicians or sound engineers/designers and such. the set is made up of nanoKey, the nanoPad and the nanoKontrol, all of which are very small (320mm across) and very cool looking.
the problem with things like this though are that i have no need for them at all. but at (only) £49 each, i find myself really wanting to get them! luckily my housemate is a sound designer, so hopefully he'll get one.
the original review has the series placed next to lots of random items so you can see how small they really are, the image below being my favourite.
