I've been using the beta version, and subscribed early. It's a shame I can't take advantage of the discount, I signed up for the annual plan :)
This has got to be one of the stickiest services I've come across. And is likely to become even stickier over time.
I'm still using 1Password, as there isn't feature parity yet (e.g. we're on a family plan, with shared vaults).
Looking forward to Cloaked Pay, as I'm a heavy user of Privacy.com already.
Any plans to add an OpenID/'Facebook Connect'/'Google Login' type service? That would be excellent for your users, though I could see services being reluctant to support it.
Off to a great start, and lots of potential for adding value.
