Feature:
It's very light-weight, feels pretty good and works really well as a controller. I prefer the non-weighted action myself. This is a very simplistic controller, but it's exactly what I wanted. The only thing I'd like added would be transport controls like the Axiom has, but the addition of the mouse controller partially makes up for that. This keyboard also doesn't have aftertouch, but I'm just controlling GarageBand and none of those sounds respond to aftertouch anyway. The M1-LE is also a nice addition, but it is a stripped down version. You get all the original programs, but only a few of the Combos and no effects. What is included is a flawless reproduction of the M1 though (which I own, so I should know). AND, the M1-LE actually works on my MAC, unlike the Proteus sounds on the E-MUs.

Quality:
Build quality seems fine for this price range. The keyboard doesn't feel quite as good as the $9k Oasys, but I can't complain.

Value:
Korg has a winner here. This keyboard is clear step up from the M-Audio 61es.

Desirability:
This keyboard is totally sexy. Looks great next to my MacBook Pro.

Sound:
Just a controller - no sound.

Ease of Use:
I don't know how this product could be any easier to use. Plug it in and it works.

Support:
Haven't needed any support yet.

Overall:
Given the price and the features, I'm very satisfied with this purchase.
