I think netbooks are really going to take off in education in the coming years. A lot of schools chose not to use them because they have less memory. But using an Ubuntu OS, you can get a ton into just a couple of gigs, and all the software is completely free. Plus, price-wise, netbooks are comparable to many smartphones. And, unlike phones, netbooks can do a ton more -- if every kid has one, an interactive whiteboard is almost unnecessary.
I encourage you to check out Microsoft's Mouse Mischief. All the teacher needs is a PC with PowerPoint, a Projector and up to 25 wireless Mice to instantly turn his or her class into a collaborative 1:1 experience!
