Re: Worst effect. Brain washing kids that Cisco and Microsoft are *all* there is.
I took a Computing A-Level back in 1996, it was all Science really, no mention of $MS or Cisco. We basically learned about Binary, Hex, How some of the technologies worked and of course, how to program in Turbo Pascal.
Nowadays, $MS has muscled in, you are expected (AFAIK) to be using $MS Orifice and such. The teachers don't understand "Open Standards" exist, they just want a .doc or .docx, full-stop.
