Interesting, though I'm not too keen on making the N810 any bigger or heavier than it is already. It's already on the outside edge of "carry everywhere," at least on my scale.

I did look for a bluetooth capable camera, but I wasn't impressed with the camera side of what was out there. I ended up buying a low-light point and shoot with SD cards. Of course, they've now announced some new bluetooth capable cameras (doesn't it always work that way?). I've thought of just using a couple of USB cables with an adapter while putting the N810 into USB host mode, and will probably do just that on the next trip.

Another option I'm exploring, unsuccessfully so far, is locating a bluetooth SD card reader. I think that would be great, having some battery-operated thingy in one pocket that can run an SD card and then make the files on it available to the N810, or any other bluetooth device. Maybe something that had a big whack of storage space on it's own too. It would be an external tethered storage space, that I could stuff the Camera's SD card in without having to muck up the N810. I've found lots of bluetooth card readers, but they are USB-attached to a computer and are both a card reader and a bluetooth dongle. Not what I want.

Sigh, maybe someday.

But, thanks for the link to the SD add-on for the N810... it's something to consider.
