There was (as possibly still is) a small compatibility issue with Nokia PC Suite and Vista after a Microshaft update... It doesn't effect the phone and you can still transfer files and install software etc by using the handset in Data Transfer mode (not PC suite mode)
Anyway - the new Nokia N96 is due out later this year, I've had my hands on one and it's basically a N95 in a sexy black dress
