My other keyboard is a gigantic 61-key beast. It takes up so much room that most of the time I just keep it stored to free up the extra space. I'm usually only recording single-note leads on it anyway, so this is a very welcome change! I'm considering just getting rid of that one now...

There's also a "nanoPAD" and "nanoKONTROL" for drums and sequencing which look cool too. Check these things out at www.korgnano.com (Please note: This is NOT a sales post – Korg barely knows I exist. I'm just sincerely enjoying my new toy :)
EDIT: If you're thinking of picking one of these up for yourself, I got mine from the cool geeks over at thinkgeek.com.
