There are two applications from the iTunes store which will enable you to use your iPad as a slave or second screen to your laptop, MaxiVista and AirDisplay This has good implications for graphics and video users but it can also mean you can extend your laptop screen to accommodate other things like chat, tools and email . The AirDisplay site gives you some good ideas. Both of the sites have customer reviews. At this stage the iPad loses its touch capabilities because it is annexed to the PC or laptop. There will probably be a work around in time because the touch function is popular.
