Brand loyalty is a tricky one when all the companies that made computers when I was at school are gone. What I did learn from exposure to primitive 8 bit machines was variety and flexibility which took me into software development. Later when Macs and PCs hit schools, the level of interest kids had in programming or even understanding computers dropped so we ended up with a generation of kids who couldn't do much more than type up a letter in MS Word compared with my generation which were writing hand coded assembly and building robots. Thank goodness Linus came along with his kernel and we were able to have a real OS on cheap PC hardware and that has given me a solid career so if there's any brand loyalty it is to Linux. While I use a Mac today (best tool for the job when dealing with a mixed environment) I'm a Linux admin and programmer by profession. The fight by these companies to control the market is bad, we need a mixture and devices like the Raspberry Pi are what we should be using to get kids hooked. Typing up letters and doing spreadsheets is not computing but seems to be all the schools are prepared to teach.
