I've tried a few different similar program but 1Password is the most seamless and easy to use. One of the most important steps you can take to making your surfing more secure is to use strong passwords and not save them in the browser. I basically never used strong passwords because it was just too hard. Now with this program - no more using a few very simple passwords for everything - you can use strong passwords and be much more secure.
The 'wallet' feature is also very handy - no more digging my credit cards out to make a purchase - it's all there.

Excellent application - essential this day and age of ever increasing security threats on the web.
