I bought 1Password for Mac at full price and I quite liked the design and basic functionality.
Reluctantly and after months of frustration, I've abandoned 1Password for a competing product.
The reason: the lack of cross platform cloud sync. iCloud integration is great but isn't available on Android or Windows. Dropbox is flaky and unfriendly.
It's pretty clear, for whatever reason, that 1Password isn't going to introduce a Google Drive based folder service for cross platform use. This is a real shame and a decision that renders 1Password pretty close to useless for my needs and, I'm guessing, the needs of a fair few other people.
