So, to anyone NOT using android or iOs...
I got my N8 a few days ago (week to be precise), and got some good apps for it.
So, first up is automatic panorama. It makes, surprise!, panoramas. It's a good app because it's free, and the N8 doesn't have native panorama support.
Second up: ( If you're interested in photography, which I assume you are, since you bought an N8!,) is Nat Geo Photo Tips. small app, lot's of brilliant advice about photography.
Third up: Swype. I don't know if you've heard of it, but it basically allows you to write, without having to write. You just start at one letter, and then move you finger over other keys to form the word you want, and it guesses and types it in for you. makes writing much faster.
and since you don't usually get countdown timers on these new-fangled phones, get Countdown Timer from the Ovi Store.
