In 2010 my local elementary deployed iPod Touch 2Gs. They bought a class set of around 50 and then bought one for every teacher and staff. The idea was supposedly the teachers could perform reading assessments using an app created by the test company, and students would use apps on them to learn. One assessment was carried out using them and the teachers complained so much they went back to paper. A lot of money was allocated for app purchases, but the IT group was lazy in handling it. They waited about a year and a half before finally trying to add apps to them. The technology had already moved by then and none of the apps they tried supported the 2G anymore. The class set was moved into a closet. I don't think there was any plan for the teacher iPods, and they remain unaccounted for and no one really wants them back.
I remember the grant total was over $100,000 for this, but I think it included the purchase of some Macbooks for the teachers, a cart to hold all the iPods, accessories for the iPod 2G, and money for app purchases.
