I think their products are pricey, but I really enjoy them.  The Q is a lot of fun if you're going to spend that much anyway, pay a little more and enjoy the big qwerty keyboard and other functions.  I could see using the Q as a lot more than a bitcoin signing device (assuming its not for your main stack) since it has lots of extra functionality like keyboard simulation, passcode storage, password generation, etc.  A really fun thing.
