I learned that the Dell Netbook is very similar to most computers.
My son has an I Pad at home and I use it quite often.
I currently have only one I Pad in my classroom. I have students take turns using it and they are responsible checking it back to me when finished or at the end of the period.
Students love using this or their personal I Pads/phones. The most serious problem at the moment, is not having enough devices for each student to use.
