For the most part, it's very comfortable.  A big reason why I bought it was to match all my sleek metallic Mac stuff, and it looks very nice with the matching keyboard wrist rest.  There are a few flaws in the material and it's very easy to get dirty.  There's also no real seam around the edges, so I imagine this will fray sooner than other hemmed pads.  I also think the mouse pad could be bigger - I have to turn my tracking speed up to cover my 27" monitor with this mouse pad, which isn't a major deal but it is a rating factor.
