Mint.com

As part of our financial learnings we signed up for mint.com. Does anyone else out there use it? I don't think it's very easy to use/user friendly. We actually signed up for it back in Ecuador but because we weren't using our cards EVER it didn't really do anything. We're trying to use cash for things back here in the States too, so I don't know how practical it is for us. I do like that it reminds me when payments are due, when accounts are low, and the goal feature. But I don't like that I can't set up payments with it. Anyways, does anyone out there have a good budget tool for cash purchases too? I wish I had a smart phone that could download those cool apps, because I've seen some good ones for budgeting cash!
