Pros: Overall ergonomics, Small Size, wireless range, accuracy, long battery life, back-lit, integrated mouse and scroll section

Cons: Some keys require awkward function/shift to use

Overall Review: I have owned somewhere around 8-10 HTPC keyboards searching to find one that is "just right". I have had this one for over 5 years and it is as close as it gets! Sure a few lesser-used key combinations can be awkward, but lets be realistic, a tiny keyboard can only include so many keys. If you are troubled by this, get a full size keyboard and then whine about the size. Also, there IS a question mark key AND a comma key as well. You just have to use the aforementioned function key to shift to them. Not perfect, but try out a few of the very strange HTPC keyboards out there and like me you might very well come back to this Lenovo choice.
