I guess it depends on how your cloner works. I use an EZ-Cloner, slap 30 cuttings in it, refill the reservoir after a week, and after two weeks I take out the clones that have nice roots growing. That's so incredibly easy, just one reservoir refill in a 2-week span, that I don't think I'd try air-cloning simply because it'd take more work. It IS cool though, and if I didn't already have something that works so well and with so little effort, I'd try it too!
