Like lot's of people i'm currently the owner of a Nokia N8. Apart from the already widely known shortcomings, it's a great phone. However, it's weakest point is 'text-input'.
Please ... somebody .. take a look at Gravity's new in-app keyboard .. and develop something like that system-wide. Decent layout, portrait qwerty, nice buttons.
Nokia announced that it will update the N8 in febr. 2011. That's a long time from now. You could be earning big money if someone would put a decent keyboard in Ovi Store.
(it's sad I have to ask developers for this .. as Nokia should have put more time on it themselves).
