Yes. The querty keyboard has been redesigned on the Matrix. The buttons are all now invdividual raised keys unlike the Duo which some people complained about. The screen also now switches instantly from portrait to landscape when you slide out the keyboard. I noticed some people complained about a delay on the Duo.
Yes the Matrix's QUERTY keyboard is good. But the number slideout pad is really flat. The buttons are connected row by row. So like, 1 2 & 3 would all be connected with a long skinny button then 4 5 &6 then so on. Really flat & small. The only thing you would feel is the 2 little dots at the ends of the 5key. But i never really use that slider any ways. Rather use the qwerty keyboard.
