I finally got one of these...it's I-KOOL! Feels good in hands (quality build), functionality is quite fantastic, very, very well thought out and implemented. Very easy and convenient to operate. PC/Mac no issues. An ultimate ergo input device at the absolute minimum. Also extremely portable if you don't want to lug a big keyboard around. But also a different animal. It's as different of a keyboard as a Datahand.
I wish I had gotten one of these a looong time ago. I'm completely surprised these aren't everywhere. Goes to show the power of big corporation titan marketing verses the little company.
Size is a little small for my shoulders/hands
What it is:
-Ergo, ergo, ergo, ERGO!
-convenient for portability
-no brainer dual use typing/gaming
-comfortable/relaxing for leaning back typing AND mousing
-an excellent input device for using in conjunction with another form of input (for a change) uses different muscles
-quiet operation
-seriously ergo...no carpal tunnel, etc.
What it is not:
-100 wpm typing.
