I would recommend playing Korg's microSTATION and microKORG Synth/Vocoder if the microARRANGER isn't yet available in your local store...the two former are out a while and should be on hand for a test drive to see if the keys will work for you, especially if you play chords in both hands...and, just to be sure, try a normal sized keyboard afterwards (or, even better, along with it) if you plan on using the microARRANGER in conjunction with another instrument with standard keys.

In other words, try these smaller keys before you buy...unless your dealer will give you some sort of return policy if it isn't to your satisfaction. These itty bitty keys don't work for everybody, especially if you have thick fingers and/or large hands.
