I am very disappointed with this Microsoft keyboard, however, I like the mouse very much. My biggest problem with the keyboard is how stiff the keys are!!!! I have never felt such stiff keys on any Microsoft keyboard before. The second disappointment is that the letters are already wearing off of the keys and I have only been using it for approximately one month. While I definitely do not need the letters to be printed on the keys to know where they are since I touch-type, I would not have expected them to wear off so quickly. In summary, although I don't hate the keyboard enough to send it back and incur shipping charges since it was reasonably priced in the first place, I definitely would not buy another one of this model and will even consider other brands if Microsoft has changed all of their keyboards to now have such stiff keys.
