I know of three districts that have deployed iPads to some extent. None of them had ANY group management software. Apps had to be downloaded one at a time, mail setup one at a time, etc. Updates? Hope your IT likes downloading iOS 8.1 one at a time...
And iOS is NOT meant for content creation. So, for example, if a student is assigned to make a PowerPoint type of presentation, there is no file directory for a kid to save photos found on the web. Instead, he or she has to go through photos where all images are saved. Want to send that new presentation to someone via email? You better hope the native app can share it via email. Oh, your file is too big for email, then let's hope the app you created your presentation in can share to DropBox, etc. And Dropbox or Google Drive, belongs to whom exactly? Is it a class dropbox, or one setup for the individual user? And then, how do we allow the teacher access?...share it as a public folder with hyperlink? Ok, then how do I send that to the teacher?...and isn't that messy to get random emails interspersed with others? Assuming the teacher gets it and grades it, how does he or she make corrections or comments, how does the kid get the notified the corrections have been made?
iOS and iPads are the LEAST appropriate OS out there at the moment for education. That's not saying they're not useful in other situations, but as they stand now, they're abysmal for anything but reading a digital textbook (which is really why they're being pushed).
