Pros: Media keys, shortcuts, design, wireless, Logitech software
Cons: A bit noisy, size
I really love using it daily. There's not many keyboards out there that offer such a great means of media access.
I find the use of the buttons at the top of the keyboard, alongside with the programmable F keys, makes this keyboard one of the best media keyboards, ever built.
The Logitech Setpoint software also complements this keyboard by allowing you to define how you what the keyboard to behave.
The only disadvantage of this keyboard is the fact that it is a little cranky and noisy. This is especially noticeable when one is typing at full speed.
Another thing to consider is its actual physical size. It is a big hefty keyboard. However, all in all it is a brilliant keyboard, one that I feel should be in front of every desktop that uses media functionalities daily.
