As someone who recently jumped from Lastpass to 1Password... I wish them the best, but I feel I'm working with the far superior product. Especially on iOS + OS x.
I've recently done the same, but the lack of support for Linux and their lackluster Windows version kinda bums me out.
Why's the Windows version "lacklustre" compared to the Mac version? I thought 1Password 4 for Windows is at feature-parity with the Mac version, they even have sync over wifi which was missing in 1Password 3.x for Windows.
