Don't think I'll be adopting the N8.
I'm enjoying the total freedom that my N900 is giving me.
1 of the big features that swung me to the N900 from the N95-8GB was the none branding of the O/S.
I got sick of the "No you can't use that on your phone" and the restrictions that providers use to cripple their devices, and all the "No you can't have the latest firmware, because WE don't think you need it".

It's a good O/S for mobile. very versatile, and I liked some of the apps that were made for it, and Nokia's acquisition of the Kastor UI breathed new life into it. Just see what making it open source does for it.
