Jim Siegl, a Technology Architect from Fairfax County Public Schools, and Eric Lai, a blogger for ZDNET, have put together a website to keep track of all the iPad pilots that are occurring at Higher Ed institutions and K-12 schools. This website is a great resource and it includes details about the pilots, the number of devices in the pilots, and links to associated articles. The website also features information for other industries that are experimenting with iPads.
You can view the website here.
