I currently have an N810 device with Android (m3) running on it. So it really works!
Maybe you could move this thread to the 'Hardware' section or make a new thread about the N810 in the hardware section to discuss experiences.
As an example, i'm able to run Android with the SDK m3 on the Nokia N810, but i have no idea yet how to install my own applications on it, i already tried several things with adb on Android system image files and then putting them onto the device but then Android doesn't start up anymore on the device.
So maybe there are some other guys here playing around with the N810 too.
I propose moving this thread to the hardware section as it was the first place where I was looking for information about the N810 in this forum.
