"Definite Curve Appeal!"4.0 starson by TwoPynts
Pros: VERY easy to type (comfortably)
Great keyboard shortcuts/customizability
Unifying USB dongle
Easy to use software
Cons: Not Mac compatible
Missing 3 Function keys?
Summary: I'm a big fan of Logitech products and this new comfort keyboard is one of the best. Coupled with the sleek M505 mouse and unifying receiver, it is a great package. I can see how it would be useful for a laptop user, but I'm using it on my PC at work. Great key feel, lots of shortcuts, superb battery life and more, what's not to like? Not as extremely shaped as the Wave keyboard (have this at home), the layout and customization is just right for me. The software is a breeze to set up as well.
Awesome product Logitech (now make it Mac compatible)!
