Content creation? You mean only English essays, right? Can the students even install and use a proper compiler or something like AutoCAD? Photoshop?
Well you can develop webapps, there's IDEs like Codenvy and there is a version of AutoCAD 360 for Chromebooks.
A heavily DRM'ed up "laptop" that no one can do anything except be forced to Google cloudservices to even login and a browser is a rational choice now?
It isn't particularly "DRMed", there's nothing to stop you dual booting a full Linux distro if you want. But really if you're talking AutoCAD and Photoshop then obviously you're suggesting Windows or OS X are the necessity.
Not to mention Google Apps and email which helpfully uploads everything to the Google Cloud.
Well that makes it accessible from anywhere and prevents data loss from hardware failure so i'd say that's pretty damn helpful in the education environment. Though having the option to upload to DropBox or OneDrive or some other alternative would be useful.
This proves that all the Slashdot talk about software freedom is thinly disguised Microsoft hate since everyone here seems to be pumping up heavily locked down iDevices and Chromebooks.
Or maybe they are finally realizing that not everybody needs/wants a fully open, infinitely configurable, high maintenance product all the time. Sometimes they just want it to do a limited subset and do it well with minimal requirement from the user. That isn't to say you couldn't dual boot and have full desktop Linux on there as well.
The whole free and open thing seems to be stagnating a bit, I mean Android is free and open but where is all the FOSS innovation? Sure there are some helpful utilities for devs and admins but that's about it. There's no reason a FOSS package or distro couldn't have been developed that provided all the innovative features that exist in Google Play Services but it didn't. It's nice for everything to be FOSS but from the consumer perspective it doesn't seem to have much advantage over proprietary.
