The N9 is quite a different experience as it has no "desktop", but the "views" -system where you see certain content in certain views. Perhaps the most dominant one is the apps-list, which received some criticism earlier in this thread. I also feel this is a move towards a style that I thought was deemed obsolete by Marko Ahtisaari, but they decided to go that way with MeeGo and now with the choice of Windows Phone 7.

The experience on the N9 is very good, and the "3 views" style UI technically works brilliantly. However, I feel that this is a move towards a dumb-phone like feel, which is reinforced in the stock apps of the device: Facebook and Twitter apps open a drastically simplified app of what we're used to and all the pages in the browser open up as mobile websites (if someone knows how to tweak this, let me know!). So the experience is very iPhone-like indeed, in the sense that you feel you're thrown back to 2009. But using the N9 is also an aesthetically pleasant experience, where the feel, sound and graphics add to a very pristine and classy experience.

The N9 exceeds in everything it sets out to accomplish and even beats some of the competition in their own game, so you can't really say its a bad device. But if you are looking for something along the lines of the N900, the N9 isn't the device for you. If you decide to go for the N9 anyway, many familiar Maemo apps are available in the Nokia Store, such as: Filebox, Twimgo and gPodder.

Personally I'm going to my operator, getting a normal SIM and putting it back to the N900 again.
