easiest way to figure is, do you prefer a mouse or a track pad? When behind a laptop do you say "Geez I wish I had a mouse"? or do you like using a track pad at your desktop.
Desktop track pads have been around more then 10 years, so what you're seeing isn't something new, just what you can do with it.
My personal opinion is that a mouse will be way more familiar. I think Apple is taking this whole multi gesture stuff too far, too quick.
