This is a great tool backed by a terrific developer. I use it to secure client files on my laptop. It allows me to encrypt only what I need secured, and then access it on the fly. Especially useful if the ability to connect applications and folders - this lets me encrypt my email and the separate Mail downloads folder all at once.

When I ran into a problem getting it set up (and couldn't access any of my data because I'd gotten ahead of myself), the developer responded to my email with clear instructions. Within an hour. At night. It's the best customer support I've encountered with any product or service, bar none.

This is a great idea, but charging for it is a bit absurd. I MacGyvered my own last spring when I was organizing a bunch of old negatives. All you need to do is create a plain white desktop picture, and then set your brightness level to maximum. Same result, and enough money left for a pizza.
