Balloons

I really like this idea. It's the modern equivalent of a message in a bottle, with the added advantage of being able to follow your messages as they travel, and retrieve others, as well.

At first, I was put off by the price — all of $2.99! — but the more I think about it, the more I believe that it's become far too easy for innovative, well-thought-out applications to get lost in the 99-cent race to the bottom of the iPhone App Store, and those innovative, well-thought-out applications deserve better.

So I'm looking forward to trying this.
