Time habituation (a short week, about) is difficult and we primarily tend to regret the good old keyboard, but once taken in hand is a marvel of ergonomics. The ability to move the "palm rest", or even remove, allowing all hands to adapt to it, the keys are easily reachable and have a texture and a very pleasant typing. The only small poor ergonomics is at the button on the stick sub (rated 15) which is not very convenient to use. The stick is well placed and although the early hours of game using it hurt thumb, we made it.
Difficult for the moment to judge its life.
A purchase I advise MMO players.
