Large, but not too bulky. I already seem to be warming up to it.The one you picked looks really large and bulky. Hows it feel?
One thing I have noticed is that I typed improperly previously... Like, if I got to type the letter 'B'... I used to use my right index finger and reach over to it. On this keyboard it is dead space where that finger goes and I look down and realize it's on the left hand side of the keyboard. Same with 'Y'... but I'd use my left index finger for that instead.
The palm pad is nice, better than resting my fingers on my metal desk tray.
I'll review in more detail when I have had more than 20 minutes on it.
