I have an N900 but still have and use an N800. I have used the h*ll out of it, and will be sad if/when it stops working. I hope development of any kind still continues. I must admit I am not sure what this MER/Mer (?) stuff is about. An entirely new OS? I don't get it. Just more applications and more polishing of what is there is all that's needed. But I obviously don't know the big picture.
