I now own one of these.
So far it has been money well spent just to be able to see who that voice on TS belongs to..... So now when Sam is rattling the Cheetos bag, then I know who to silently curse for all the noise...
It is a little difficult to get used to. The extra bank of keys on the left (the macro buttons) sort of throw you off.... I've hit the G1 button many times when I actually meant to hit esc....
Overall I give it a big Dwarf thumbs up.
