Jogs for me are still the best way of manipulating the music, especially for manual beatmatching, but also for cueing up tracks and such. Still, there are examples of controllers which have touch strips instead of jogs (saves a lot of space after all). With your fear of inadvertently touching them … well …
Stay with the software you like/love/know well until there is a very compelling reason to switch. Not sure how big the jump to Djay Pro is, but the good news is they support a large number of controllers.
Backup, especially if you are a Djay Pro user, is simply done by adding an iPad to your collection. Get a small PA mixer like the Yamaha AG03/06 or the MG06, hook your controller and your iPad onto it (and a mic should you so desire) and if something happens, hit play on your iPad, open the fader on your PA mixer and you are in business again.
