My biggest problem is that its actually too long to thumb type effectively. All that other stuff people have said goes too, but it gets quickly uncomfortable to type using thumb-style because its a little long. Also I end up crossing over my fingers (then I really can't see what I'm doing) when "two-keying" some FN/CTL key combos, etc due to the fact that the FN and CTL keys are only on one side of the keyboard.

I wish that the | key and TAB keys were there though. I have to use xmodmap to get that function right now. Who decided the yen and Euro deserved a permanent spot rather than TAB?

That being said, its decent enough given the space they had to put it into.
