I realize teachers like to pontificate as they indoctrinate, but your preposterous proposition is absurdity incarnate.

Just buy a laptop and a podium. Fujitsu and Lenovo both sell (less than) 1000 USD tablets and flip screen as well which run windows. You've reduced your entire IT cost to 600 bucks if you make the responsible fiscal decision.

Oh, but I know your rebuttal already: NO MOMMY I WANT AN IPAD, I WANT TO BE LIKE THE COOL KIDS, WUAAHH WAAHWAAAAH.

Less english, more accounting.
