The N90 is the only Nokia N-series I had seen before, and has entirely too many hinges to be something I'd consider usable with a single hand.
- New hi-res screen and improved screen fonts.
- Fast. Like no other Series 60 before it (although based on previous experience all "blank" Series 60 phones seem fast before you start filling the memory with contacts, photos, etc.).
- Decent quality pictures (although the Carl Zeiss lens doesn't look like much of an improvement on the K750i).
- High framerate video.
- Same camera UI as the N70.
- Big, Heavy, Fiddly. Feels like a Transformer's pet rock. Doesn't carry comfortably in trouser pocket (unless you're an XXL sort of guy/gal).
- As usual, not enough RAM to last more than a couple of hours in my hands. A couple of shots, a few contacts, and poof.
- Incompatible with some old applications I had lying around (might be this revision, but it's common enough between different Nokia models).
- Lens gets dirty easily.
- Camera stick and button are fiddly.
- Memory slot cover seems... likely to snap off, like in the N70.
- New charger plug (oh yes, they're changing the power adapters, and it ships with... an adapter for the adapter)
- No infrared.
