I went to grade school in Redmond, WA. Interestingly, there was seemingly no Microsoft presence at all - it was all Commodore PETs and Apple IIs.
I wonder if the attitude in some schools is "everyone has a computer at home and knows how to use one now", so they shrug their shoulders and feel like there's nothing left to contribute. The kids print out or email their homework from their computers, so maybe they think that's all buttoned up.
I wonder if the interest in programming is even there anymore. When I was a kid, it was amazing to draw lines and colors on the screen (and sometimes, colors weren't even an option!). These days, I wonder if kids still delight at making the computer render simple drawings and programs, or if XBoxes and Facebook have rendered such trivial programs uninteresting.
