I work in a school in the UK. I'm currently having arguments over exactly this subject: the powers that be want to roll out Google quickly (having already wasted *lots* of money on some iPads a few years ago, and Asus eeePCs before that). Apparently I'm the only IT guy across the multi-academy Trust who's been kicking up a stink, the rest have just rolled over and moved to Google, Chromebooks and all.
We presently have just under 1000 PCs and laptops running Windows 10 and Office 2016 / Office 365 (the latter for its easier integration with Gmail - feedback is people hate the Gmail website but get on well with Outlook). I'm doing my damndest to make sure that any new devices also run Windows and Office, so as to hook into our existing network. Pointing out that cheap laptops can do everything a Chromebook can, plus hook into our existing infrastructure has delayed the Chromebook push for now (they've already had experience with how awkward printing / file access was with the iPads). I still strongly feel that this whole one-device-per-child thing is a colosal waste of time and taxpayer money, but the sellers in education do a really good job of painting a Utopian picture of classrooms full of kids all eagerly collaborating with teacher. (What actually happens, of course, is a good chunk off them instead browse photos / websites / play games etc).
It doesn't help that there are political moves afoot to force a move to Google, such as banning removable drives (which I'm resisting, currently enforcing Bitlocker for write access). Banning removable drives would, of course, stop our SLR cameras in Photography from working, stop teachers recording the children using our video cameras on the school farm (for Animal Care), stop audio CDs being burnt for speaking and listening exams in French, stop them recording performances in Drama (again, on nice video cameras), stop potential teachers and people coming in from outside using memory sticks for their lessons / presentations and much more besides.
Google Apps isn't perfect either - as well as having less-than-great viewers for Office formats, it has no answer for Access, something which is deeply embedded in the curriculum. That means we need Office and proper PCs in our IT suites... and as such we may as well keep it elsewhere too.
I suspect, though, that eventually moves will be made to move our network storage to Google Drive, despite the lack of being able, for example, to get an Access database back from last Tuesday, as it's been overwritten by mistake. They're already planning to migrate email away from Exchange to Gmail by next summer.
Mind you, there is one thing from all this. I was brought up with Windows (2) and Office (Word 1, Excel 2) at school back in the 90s. It's quite true that if you get them at school, they'll carry it over into their adult lives...
