Thank you both for your replies. I guess I'll buy it. I do like it and can find nothing like it.

I am also evaluating Ascendo DataVault right now, and yea it would do the job, but not as well. For one thing I don't want to have to input a password in order to make a note entry, and since DataVault will probably be my secure app on the device ......
Also, I love the search feature in IdeaMatrix.

So I guess there's a reason my search for an alternative was fruitless. The Rexguys have the only game in town right now.
