Dave Castelnuovo – Owner, Bolt Creative“I would like to see a personal anti-grav device built into the ipad 3 so that I could sit on it and allow me to hover around instead of walking. Kind of like of like a Segway, but without the Segway. Seriously though, I’m not even sure what else they can add to the iPad.”

Other suggestions include Flash support, 4G data support, “retina display” and more. Regarding Flash, I think Castelnuovo’s hoverpad idea has a better chance.
