I recently bought one of these, and I love it, for both its size and its layout. I would really hate to spill a Cup Noodles on it like I did with my last keyboard.
I have just one problem with it. I accidentally hit control-'a' while typing a long writeup and instinctively hit backspace, deleting my whole writeup. A combination of the control key being right next to the letter 'a' and Internet Explorer's (I can't use Linux right now for a reason I won't explain here) lack of an undo option caused me to stop writing that writeup and start writing this one. I guess having control and 'a' right next to each other might cause some problems once in a while because of the often negative consequences of selecting all the text and hitting another key.
