Reply to "Airplane" keyboard advice

Hi all,

I'm flying a lot and would like to buy a mini keyboard for making music on the plane/at the airport/on the road.

Pitchbend would be nice, but only if it's usable.

There are a lot of small laptop-sized keyboards, but probably most of them are toys. I'm looking for something really usable. I'm not interested in the best brand, or something that will satisfy my gearlust.

Any advice?
