Yes, awesome it is. You may also consider an equally super-sensitive GPSlim236 by Holux, also based on the new very powerful SiRFstarIII chip. The 338 is Bluetooth only, and the 236 can be used either as a Bluetooth receiver or via USB. And you can actually use both connections simultaneously ;-)
The 236 however has a smaller battery and I only get 10 hours out of it (which is fine for my purpose). I managed to get around 17 hours from the 338!
