It makes sense for Nokia to discontinue manufacture of the N800 because it has the N810 for a replacement. N800 availability also wasn't cut off when the N810 was released. The N800 has however not been abandoned from a software perspective. Your N800 like last years PC has still grow in capability as new software is written. It has certainly benefited from the OS development that's part of the N810. I think the big question for existing users is will the "N900" be a fork or will the N8x0 community continue to benefit from the OS and application development associated with this SIM based product. It is in Nokia's best interest to continue to leverage the software developed by the Maemo community.
