I may be behind the curve a bit, but years ago when my mother was teaching in the Boston school system, Apple Computer offered deep discounts to schools to use their computers. I’m not sure where Mac and Apple relate but I would guess that Mac may be following in their footsteps. Thus, if kids are exposed to only Macs at school this may account for the heavy incidence of Mac use.
Someone once said, News is information that someone, somewhere, wants to censor. Everything else is advertising.
Apple is the company that makes the Mac.
The program you are referring to occurred in the 1970s to the 1980s when Apple first gave one Apple II to every school in the US. I think the total was about 30,000 Apple IIs given away. Apple had, and continues to this day, an Educator's Discount program which allows anyone associated with education (including homeschooling) a 5-10% discount on specified Apple products (unfortunately, not the iPhone, drat).
Most of the students you see in the picture would not be those who have been influenced by the program because a 10% discount on a $1000 iBook or iMac or Macbook computer cannot compete with the $500 laptops and $300 desktops available in the low end of the Windows PC world that many schools of the 90s and early 2000s bought looking only at initial cost rather than Total Cost of Ownership. (Macs have consistently turned in lower TCOs than Windows PCs in reputable studies.) Most of these students came from PC using homes since 90% of the world is Windows centric.
This particular school strongly recommends Macs. Others recommend Windows PCs. However, the trend is strongly going Mac...
