I don't use SD, I use other things - all of which have failed on me at some point.
Learning to fly, no: use the way you are taught as primary nav.
For qualified pilots - absolutely use moving map GPS as primary nav, it's very good for it. Skydemon is a good package - that I don't use it is just my personal choice.
Just don't ever let yourself get sucked into using it as your sole navigational source. A printed out PLOG and paper chart are perfectly adequate as a backup, so long as you use them.
