The touchscreen works over-all well but it's the right side that's getting worse and that's the area where is browser up/down slider. There's no scratch on screen yet so it's durable, 770 screen got two nasty scratch on it and those came easy, too easy. Sometimes the N800 screen is working better sometimes not. That's why I think it's depended on software, again I might be truly wrong about that. Anyway , it's something that will be fixed and maybe I'll have to take it to service finally . We'll see.
