Love the ipad. I'm finding that customers gravitate to it. "Oh, is that the ipad?!!" Easy way of getting undivided attention.
As for the other benefits, I'm still learning. Have not had it long enough to use it to it's full potential.
The battery life on it is amazing. Way better then anything else I've tried.
I tried the Augen from Kmart - had it for a day. Although it has the google app market installed, it's useless because you can't download any of the apps. Augen failed to make a deal with google to allow downloading. So the thing doesn't do hardly anything. Not to mention the 3-4 second lag time for displaying pictures.
