Another area of growth is "mobile gaming" starting at some of the casinos. It gives the player the ability to play from anywhere on property with the use of a game pad sized unit. You can chose your game and denomination, and play in your room, bar, restaurant or poolside; all done through wireless links.
The providers of this technology should see a marked growth as the domestic gaming economy improves.
Don't take my word for it, Do your own research! Then you will know it's true!
