one thing i noticed today is the communication history for a contact. very nice. spans all communication methods.

one other thing i didnt 'get' until frecently is that you can have different preset sets of statuses so i have one for in the car which sets me offline for most except most critical accounts and i have one for home wifi where all accounts are set to available, etc. very handy.

i also just realized that while you are on home screen you can just start typing to look up contacts.
