I supposed it boils down to what you really want out of it. If it's to file away for eternity to know 'more or less' where you were at a given time, then I suppose those applications are 'ok'. If you want real accuracy, then they suck. I used Spotwalla for a while but got tired of the lack of data recording. Compared to what my SPOT was putting out, Spotwalla was recording less than half of it. The good hing is that it was now logged forever whereas the SPOT page deletes the data after about a week. The bad thing is that Spotwalla logged it so poorly that I stopped using it. Now, every time I finish a ride which I've tracked though Locus I just export it to my dropbox account. If I want to recover it for whatever reason I have it there. Its seldom that I do but at least they are there. If you don't mind the privacy concerns, I'm with ohgood on the GoogleMaps timeline. I can go back almost a decade with it and takes zero effort on my part.
