Thank you everybody for such detailed replies

On my N900 I mostly surf the web, listen to internet radio and music, chat on Yappari, watch YouTube videos and take some pictures with my camera...
the thing that I want but I dont have is better photo viewer(album), better flash support and a nice browser because I use opera which i okay,but not great. I also need dedicated Facebook app with notification system, offline navi and maps and I also need some cloud storage implemented in phone system... Can N9 serve me with all these apps?

EDIT: I also need documents viewer and simple editor, for working with word, and pdf files

And how hard is it to get used to on-screen keyboard after N900?
cheers
