In my view, Director Deasy's persecution is politically-motivated. The choice to go Apple was the result of successes in various Magnet and Lab Schools, conducted prior to the service agreement with Apple. Multiple vendors were evaluated during the Magnet / Lab development process. There was no opportunity in the process to put it out for three bids during the actual procurement process, because the other vendors were eliminated prior to procurement.
Our technology program is funded by our PTO, which is a becoming a common trend in many public schools. It's much easier for our PTO to raise $80K/yr for tech (we raise more than that, to fund other programs) than it is for LAUSD to indemnify the purchase or lease of tech on a district-wide basis. We will likely continue to choose Apple products, with the primary motivation for that decision coming from the instructors, and secondarily, the build quality being able to stand up to student use at school and home.
