I gave the keyboard 4 stars, as it is a good quality solid keyboard which works as advertised, but nevertheless I personally don't like it. I now really wish I had bought something else.
Why? The keys have a very low profile, and as a touch typist you can't just put your fingers on the keyboard and immediately know where you are. The Ctrl / Shift / Esc keys are especially bad in this respect. I find myself frequently hitting the zoom keys in error (next to the Ctrl & Shift), and also the email key in stead of the Esc key. The function keys in particular are a triumph of bad design, being even smaller and flatter than the main keyboard keys. They aren't grouped in fours either which makes it worse. Just try hitting Alt-F4 to close an application and you will see what I mean. Very pretty, but the ergonomics are poor.
I'm sorry I can't be more positive about it. I gave it 4 stars, and for 90% of people it should be fine. For the other 10% of people who are touch typists, look elsewhere. If possible, try it out before buying.
