I agree with the low profile RF keyboards come in.
A bit more comfortable, even without keyboard palm rest. Also I like the round/organic design, nothing wrong with boxy ones though.
Also have the Leopold FC660C, and this one, I find a bit too high in the front, especially without palm rest.
Gotta have PBT for sure in this price point. Unless, the novatouch case was a bit more distinctive, I would ever consider buying.
Like the emblem 'REALFORCE' very very much!
