It's maybe a stupid question, but what can you do with a N97 that you can't do with a N810? (except the phone functions obviously).
The N97 unlocked must be around 700 USD, while you can by a N810 for around 200 USD, not mentioning the higher res of the N810, major bonus for browsing the web. Ok, the N810 do not have 32gig of embedded memory, but microSD cards are cheap now.
Just don't get the point.
