Schools vs. Universities
The perspective of the educators is a great take away and it makes perfect sense -- if the transfer of knowledge is based on text, audio, video, graphics and interaction, then the differences between a device that has, for instance, 1 GB of ram vs. a device that has 2 GB of ram is of little concern. The software should focus on the lower end because, that's where the mass resides in the market. Facebook's mobile app is a good example here, they write their mobile app with 512mb of ram in mind -- maybe, that's what their data is indicating towards. And, one of the reasons for Windows Vista to fail was because it required extremely powerful hardware for its time.
Universities on the other hand are a bit of a mixed bag, the majority of departments can benefit from the standardization of mobile devices. However, they will be a few departments that require a unique ecosystem. For example, a department that specializes in teaching, Big Data skills, will requires the Big Data, infrastructure (cloud resources) as well devices that have already been experimented by companies such as, SalesForce and SAS, etc.
