To be honest; for a newbie Windows is absolutely fine and dandy. I have a W7 install for gaming and other bits that goes just fine :) And Linux is still too much for the vast majority of people.

But from the chapters perspective you have to think about vulnerability; and Windows is quite vulnerable. You don't want to have a laptop with malware hanging around, and Windows attracts it too easily.

If someone uses the laptop, enters their email acc details and subsequently gets infiltrated that's more than embarrassing for us :)

Which is why I recommend something like Chromebook - because it's very hard to make it do anything else except web browsing.
