Just got my brand new 5800 XpressMusic 3 days ago and I'll post some impressions here:

 Design

 In my opinion, the phone is very good-looking. Nothing to compare with a Nseries, but we have to consider it is not a high-end device like the N96, for example. Although, got disappointed with the phone casing, there is a little gap on the top right corner, which makes a cracky noise when you press that region. Searching in the internet found out it is a common issue ...

 Multimedia

I'm really satisfied with the multimedia features of the phone. Watching videos, listening to music, browsing through the photos and surfing the internet is just as good as it could be But the camera ... what can I say? It barely looks like a 3.2 megapixel camera. N73's camera was better than that! Downgrade here ...

 Touch UI

I was thrilled to try a touch interface in a Symbian phone. And they work nicely together! The 5th edition still has much more to evolve but it was nice to see it is in a good stage already. I really enjoyed the way they ported the Symbian plataform and adapted it according to the needs of a touch-based device.

  Battery

The battery is just much better compared to my N95 8gb. It lasts easily 2 or 3 days with intense use, so it should last a lot with normal use.

Conclusion: I'm really happy with it, since it got much better than the prototype I tested last year and seems very good for a first touch-based device by Nokia using Symbian plataform. Can't wait to test the N97!
