If you ever wanted an illustration of how far computer technology has come in a single generation, this video portrays it well. A bunch of kids who’ve grown up with Macs, iPads and iPhones, and for whom apps and the web are as natural as breathing, try their hand at an Apple II – starting with the challenge of how to switch it on.

Scarily, I’m old enough to have used an Apple II and now feel slightly nostalgic, but I don’t think I’ll be trading in my MacBook Pro anytime soon.
