Was just playing around with DM and QR codes on my E51 and had the thought pop into my head about using them with my N800. Glad to see there was previous interest and though I haven't found anything N800 specific yet, the ZXing project sounds VERY interesting. http://code.google.com/p/zxing/ I've had the same concerns as Texrat regarding the N800's camera, I'll hafta look into the spec a little more to see, but one application I was reading about on my phone that excited me for the N800 was the ability to import bookmarks via these little images, that would save me tons of work trying to get them on the N800 otherwise. Would also be a handy supplement to the touch keyboard for visiting links, importing contacts, and calling people. So many uses, so little time.
