Looks like there's another product in the category of GPS logger + compass + bluetooth: the MN500 from "Themap", a Korean company. Can't find any pricing info yet though, not even on their home page... the product was only recently launched.

specs - Touch_Panel, 3.5"Transflective LCD, Bluetooth, Compass, Altimetric Barometer, 2.4GHz Bike_Sensor(ANT+), CPU ARM9_2442 @ 400 Mhz - you could probably run Linux on this thing, if it's not running Linux already.

I suspect again though it will be rather pricey.

edit: added specs link
