Eric points us to Jott.
You call a toll free number from your cell phone, leave yourself a message and it types it and emails it to you. Perfect for creating to do lists.
Even cooler, you import a bunch of friends or colleagues and you can send them all an email at once via your cellphone.
I have no clue how they make money, but as we say online, they'll figure it out later.
BONUS: Phoebe points us to this very cool, very cheap way to make a website. I will probably steal this idea one day, but wanted to be fair and point out that this is where it came from.
