"The line must be drawn HE-AH!" Jean-Luc immortal words from Star Trek: First Contact.*
One of the biggest anxieties my technicians have about students and staff bringing their own devices to school - smartphones, laptops, iPods, tablets, netbooks, Kindles, Nooks, and who knows what - is that we will be expected to "support" these tools in the same we we maintain, repair and troubleshoot school-owned equipment.
"Even if we had the time, how can we be expected to know every operating system of every device - and every app a student or staff member might want to use?" A legitimate question.
So we have "drawn the line" by stating that the district's responsibility ends at making sure personal devices can connect to our network. Once that's done, it's up to the user to figure out the rest of it - how to connect to GoogleApps. How to view Moodle courses. How to sync calendars and contacts.
At least that is the official rule. In practice we do everything we can to help people use their tools well.
I am proud to say that in our district that our techs are also educators.
