hum... playing with a nanokey for the last 20mins, borrowed it off my mate. Its cheep as chips, in a bad way. I can only see this being used on a plane or bus, if you must. Just way to plastic, key action... there is none. Reminds of the really old ataris with the contact keyboard. Keys tend to miss notes sometime too if your playing fast. I guess if you're a kid and never used a really good keyboard before they'll seem fine!
Don't know still thinking about this, might keep it just for club gigs, when I have to play in the dj booth... I imagine it will break pretty fast too. Its just too flimsy... shame I really wanted this to be just a little be better built.
