Jott

I've known about Jott for quite a while now, but I haven't really started using it until I had a longer commute (the new company is in Mountain View).  What I like about Jott is that I can add their phone number to my speed dial and when I come up with an idea or a todo or anything I can just call them and record a message for myself and they take care of the speech to text translation and it is ready for me usually just minutes later.  It is simple, but I use it just about every day.  So if you have a decent commute where you drive and can't write things down when you get ideas you should give Jott a try.
