Do students have to buy a particular model?
No, there are several prior and current models of laptops which meet the specified operating characteristics. In conjunction with the teacher preparation program at The University of Texas at Austin, Apple has offered an iBook laptop which meets the requirement at a very low cost to students. Upgrades and other, enhanced or more powerful, laptops are also available for purchase at an educational discount. See the Campus CompUTer Store Laptop Initiative webpage.
