Pleasant, high-performance keyboard
After testing several wireless keyboards that wore out quickly and struggled to keep up with my typing, I have to say that I'm very happy with this one so far.
It keeps up with the pace, the battery lasts long enough (one charge for 3 weeks of fairly intensive office/development use) and the touch is very pleasant.
The only criticism: the presence of PC and MAC layouts is a good idea, but there should have been a visual distinction: you end up getting mixed up between the two.
