I've been using MMS in the most under-utilising manner: Sending "don't forget" text notes to my gmail. I bet some of you will say, '50cents for text?'. But to me, it is 50cents to remember a good idea.

37signals is taking this idea even further. To be precise, having that as just one of the feature of their secrety-next-kewl-thing: Backpack. I await.

Full disclosure: Yes, I'm a 37signals fan. But, these days, who isn't?
