If you come from a regular user of N900, the N9 is a toned down version of it. You'll love the UI and the everyday use.. but you'll miss a lot of features. The video reviews don't do it justice.. if you REALLY want to know how it is.. then borrow it for a day and try EVERYTHING on it, not just camera and browsing around.

If it's all slick and everything you wanna do works fine.. then go ahead. If not, the new Android phones are better for you.

If you do decide on N9, try to get the white one. The black housing looks awesome, but is very very prone to finger prints and has poor adaptation to extreme weathers and fades out.
