I did have to re-purchase it for version 3, but I use this software every day and its worth every penny. Keep it up, agile bits!
However, I tend to think that AgileBits over-charges for 1Password and I still haven't upgraded to the new version since they moved to the app store and tried to make me purchase the same version I had already bought(just to move to app store distribution model).
I bought the family license which gives me 5 users I believe, but I still have to buy the app for all iOS devices which in my house includes a total of 5 devices (at 9.00 a piece right now...that's on top of the 70.00 I spent for the family license). They don't, however, charge for the Android version which I find a bit odd since they charge for iOS.
1Password is absolutely essential to my flow as I use hundreds of personal sites and accounts, and in a pinch the 1passwordanywhere html-over-dropbox version is incredibly useful.
One of the biggest features is that when you sign up for a account on a given site, 1Password browser extention will capture that info for you - you dont have to enter it into the UI, unlike with some other managers. This makes it very usable to share passwords with, say, your spouse for shared accounts.
Any way I can get the 1Password+Dropbox goodness for Dashlane without paying $20/yr?
I've been unhappy with Keepass for a while on OSX, specifically because of missing features like AutoType. How does OnePass compare?
Bonus question: how easy is it to migrate my library from Keepass to OnePass?
I find LastPass premium a much better value. You give up a little control for a lot more convenience and clients for any concievable platform.
“Free Upgrade – Purchase 1Password for Mac or Windows today and receive a FREE upgrade to version 4 when it becomes available.”
I'm glad that they chose to change their mind on this one.
I guess I was cut by Hanlon’s razor once more.
1Password is by far (IMO) the nicest and best way to manage passwords (and generate single use passwords). The only downside is its expense, so when it's 50% off, that's good news for HN.
(I have no affiliation with 1Password)
I guess you're arguing that the upvotes are coming from happy users that are lending their support by clicking an up arrow. That just feels weird for HN.
"faced with too many choices, consumers have trouble making optimal choices, and thus as a result can be indecisive, unhappy, and even refrain from making the choice (purchase) at all. [Even when making any choice would be better than not making any choice at all]" 
What I'd really like is a self-hosted server for sync (webdav or something, or imap-like), but I'd tolerate a server hosted by a trustable third party (Agilebits would be ok).
I really urge you to try them, it really is a personal preference thing.
Edit: oops, this is assuming you meant you were on Windows.
There primary focus is Mac users that sometimes boot up into Windows.
Therefore the app itself looks totally misplaced and does not follow correct UI standards on Windows.
They don't support Windows 8/RT Modern apps.
The Windows Phone 7 app is just lackluster. No edit, just read only.
Only Dropbox integration and not SkryDrive.
The UX (and design) of 1Password is way better.
But another important reason is that LastPass is a central service where you have to (at least somewhat) trust them to not screw up since all your (encrypted) passwords are on their servers. With 1Password there is no such mandatory central service.
I'd say the only reason to use LastPass is if you're cheap, or if password-sharing is a daily exercise for you.
The Android app is read-only. It gives you read-only access to your 1Password database in Dropbox, but that's it. It works, but they really need to give it some love and bring it up to par with the iOS version.
Guh? I've got KeePass+DropBox on my Linux laptop, iMac desktop, Windows 7 work desktop, and Android phone. What's missing?
I'm sure it is possible to get KeePass working smoothly but I'm also happy to have paid for what feels like a better solution to me.
The new iOS app is prettier, seems to be a little more secure (requires the master password, instead of just using the quick password).
