Summary: Why are you trying to reinvent the wheel? Curved design is AWFUL. Bought the similar looking HP version of this with my desktop about 2 years ago. Didn't notice the curvature in the picture initially. The pinkies are the shortest finger, yet those keys are the farthest away! I learned to type on a straight keyboard. Everything is just slightly off due to the curvature. I've never made so many typos in my life.
Summary: I actually kept this in the box for a while, because I thought I didn't have the time (or energy/brainpower) to set it up and install it. I took it out of the box and I think it took two minutes to set up! The batteries are even included!!! Everything just worked right away! Even all the feature buttons! I bought this for my new laptop because I hate laptop keyboards and like the ergonomic ones better. It's so worth it!
Summary: This Combo is the worst Logitech product I've ever bought.... and I have a lot of their products on several PCs. There is no connection between the software and hardware. Even using the latest download from their website, the components never "unify" with the PC. Had to use a wired keyboard just to type this review. I am completely disappointed with this combo. Maybe I just got a dud, but buy this at your own risk.
