I don’t know much about the HG20, but I have a Vixia HF S100 and it’s totally easy to use. Should be a pretty similar deal… Transferring to a computer could not be easier – the fact that it is on a disk already instead of on mini dv or dvd makes it much less complicated. As far as editing, that depends on your program. I personally use Final Cut, which is complicated at first but gets easier. iMovie is pretty self explanatory and easy to get used to. I’m very happy with my Canon, I’d recommend it to anyone doing amateur video production.
