Any question answered...

I'm in the market for a GPS, but ideally one that will just track where I've been. I don't really need one to navigate by, directions written on scraps of paper, or other people's knowledge will suffice for the time being. So, does such a product exist, and are they substantially cheaper than one that will allow me to navigate (give maps, directions etc)?

I don't know if this has been answered yet or not but there is an App called My Tracks. I think every GPS will do some of what you don't want but this will at least record what you've done. And I think it analyzes it all, too.
