Personally I think this democratisation of technology has been a very good thing.
Catering to the masses has forced the IT companies who used to cater to geeks & nerds, (disclaimer - I am one), to cater to ordinary people, making things easier & simpler to use for everyone. And please don't think that being simple to use makes it simple under-the-hood - it takes skill to do it properly and iOS sales show that the fruity one is on the right track. This can only be a good thing as it now forces others to up their game.
Whether the tech-heads like it or not, using facebook, surfing the web, watching cat videos etc etc are all legitimate uses of a computer, which is after all nothing more then a tool.
The day when I am no longer the default support contact for my family & friends merely because I "work in computers" is drawing closer every day :-)
Oh, and OS X may "look" more like iOS but it'll still be a "proper computer" for those that need it to be. Apple needs the developers to keep making the apps, which in turn brings in the "normal" people to buy their hardware.
