I've the Pro one. For the normal typing, it has been great for me.
For the shortcut buttons, I only use 4 of the buttons: +/- volume, mail & calculator. The rest are not as useful, especially those for broswer like Back, Forward, Refresh, Favorites, Home, and Stop (I don't understand what's the Stop for. We can press the Esc key to stop loading and why MS just so dump to build another Stop button there).
Everyone said they buy this because it has 2 USB ports. Actually you only get ONE USB port. You have to plug in the keyboard's USB into your PC. That means if you originally have 2 USB ports available and now you get 3 USB port available. The advantage is that, you don't need to mess around your PC's back panel all the time if you always plug in and out some USB devices.
