I have been a Mac user since the 1980s, and I've had years of experience with the good, the bad, and the ugly in the applications department. If you don't own an iPhone (iPhone integration if terrific), and if you never visit more than a few web sites, you may not need thins software. Chances are, you're far from that description, and then you NEED 1Password. Imagine never forgetting website IDs and passwords. A quick click using a stable browser plugin in your toobar and you're in. Imagine having all your software registration codes and other details of purchase as your fingertips. Imagine encrypted access to all your important numbers--credit cards, social security numbers, etc.--readily available when you need them. Imagine having this available on your iPhone as well. Oh, but that's not all! They are perpetually working to improve the software even when you couldn't imagine how they could make it any better. On top of that, their tech support is prompt, courteous, and efficient. What else can I say?
