Excellent product - makes my passwords far more secure, remembers them all for me (hundreds already), and allows me to syncronise very easily between my computers.
Add this to a developer - user interaction the likes of which I have never seen before and I have to say this is the best product I have seen for ages.
Still expanding regularly on the feature set too - although I can't think of much more they could do, I am awaiting some secret developments that are apparently going on??!
The iPhone platform needs some work, but this is made near impossible by the restrictions apples has put on the iphone browser, so on the phone, 1Password is not so great, but nothing else is either!
