Pros: This keyboard features a comfortable, balanced ergonomic design. The keys are ever so slightly curved for comfort, but not in an extreme fashion like the Microsoft keyboards. Wireless is reliable, I have never had a problem with random disconnects or lag. Keys start out having a soft but sturdy feel.

Cons: I use this keyboard in an systems analyst role at work, so naturally I do a lot of typing. Between programming, writing technical documentation and at lot of command line work, this keyboard is my workhorse. Unfortunately the keys become stiff and sticky over time (about 6 months for me), and this makes it a chore to type on. I am currently writing this review on this very keyboard and have to hit backspace more than I like due to typos resulting from sticky keys.

Overall Review: Great keyboard but doesn't last. If you are a light, leisurely typist this keyboard fits the bill, but don't expect it to last if you're a typing fiend like me. I am now in the market for a replacement but have limited options at work. My department only gives me a choice between two or three models and this is one of them.
