Many of us on this forum are quite content with our N810 and N800's. There is only two things that my N800 cannot do. No Skype with video and I cannot watch NetFlix movies. Other than that, there are apps for just about anything that is needed. Many of the apps that you had on your N900 were originally N800 apps. Just like your N900 there is an app manager that downloads from repositories. Be more specific with your questions.
