I can only say that after having using a N800 for a while, with the latest Diablo release, I feel it a little fragile and slow, but still gets the job done (after some research). It is a swiss-army knife, but with some blades missing, some that I need to add on my own using complex instructions and others that doesn't seem to match the set.

I hope that Fremantle has the impressive and robust UI that the Palm Pre is showing... It has a OMAP 3430 inside, and it shows. I have been a Nokia user for many years, and I know they trade UI/usability for raw features, but improving user experience is something that is getting overdue for them.
