Summary: Able to use the cordless keyboard and cordless mouse with the ones that came with the iMac. Having both gives me full flexibility based on how I have the iMac set up. Only irratating thing so far is that the cordless keyboard has no indicator if CAPS lock is set or not.
Summary: I had been looking high and low for a wireless keyboard with a 10 key. This is the 3rd one I tried so I was prepared to send it back too. I find my self using the mouse a lot more than I thought I would. Very easy to install, plugged the bluetooth it into my MacBook and began to use it. I don't like that it takes up one of my 2 USB ports, I thought it would connect with the bluetooth already installed in my Mac, but it doesn't. I am still happy with it.
Summary: After spilling water into my Mac Keyboard, I decided to buy the cordless Desktop S530 keyboard and mouse from Logitech. Not only is it valued priced, but its preformed much better than expected. It installed easily and required no fine tuning. I especially like the solid feel of the keyboard.
Pros: Comfortable Design, Easy To Clean, Great Features, Highly Compatible, Quiet, Reliable Performance
Summary: I only ordered this since my old keyboard wouldn't interface with my Mac Mini, but so far I've been very happy with it. Programming the mouse keys for specific functions is not intuitive, but is not hard to do either. The keyboard has a good feel as far as the size (I have fairly large hands so small keyboards are a pain) and the keystrokes feel solid. I still haven't played around with the controls on the keyboard. All-in-all a great keyboard.
