I bought an iPad for my daughter, I did not think I would have any interest in it. I have change my mind though.
I can sit by the pool or on my couch, use the built in VPN to connect to my office, then VNC onto my office computer and work on MS Office or Quickbooks or anything else that is on my computer. I hardly ever use my laptop anymore. They are really incredible little devices. Recently, driving from Cooperstown to NYC, my wife found an incredible deal for a room and booked it.
If you have not tried one of these things you should. They are pretty amazing, small, light, easy to carry around. I can create word or excel documents, print them, enter data or run reports in Quickbooks, print those reports, print checks... There is a lot more to these devices than a lot of people know.
