I have spent the last 3 months since my N900 contract finished looking for a replacement. I did not have the N9 in mind but set a list fo criteria that any replacemnet must meet:-

Ability to play music via uPNP or DNLA.
Decent Camera
Skype, but not video
Drag and drop transfer of music and video etc
Quick interface
Micro SD storage
... and a few others.

I kept comming back to the N9 and given the 64Gb storage capacity I could overlook the lack of Micro SD slot.

It is arriving today and "I'm as excited as a very exciteable person who has a special reason to be excited".

But after all that list writing and deliberation it only took 1 minute of playing with a real N9 and I was sold!
