I would.
My wife, for example, is quite averse to change. She likes her Win7, hates OSX - never gave it a fair shot when I bought our Mac Mini. She doesn't even really get along with our iPad. Not that she can't use it, she just doesn't like it. She's pretty set in her computing ways.
When I installed Win8 it took her 15 minutes to get the basics. The only real issue she struggled with was switching apps. Once I showed her the different ways, she fell right in to it. She enjoys the metro UI, especially the live tiles. She likes using some of the dedicated site apps - as opposed to having to use the browser - she likes the social integration, notifications, etc...
I like it too. I find the Metro UI pleasing to look at and no obstacle to effectively using the machine. I also like some of the apps quite a bit, social integration, notifications, all that... What I really like are the underhood improvements that seem to get me better battery life, faster boot/resume times, and a generally more responsive and fluid user experience.
Not saying it's perfect. For example, allowing split screen only by thirds in the metro UI is dumb, imo. Especially with widescreen displays.
Still, the only thing I feel like we miss out on with our Zenbook is that it's not a convertible. Until Win8 I generally thought the idea of using touch alongside a full desktop OS was gimmicky. Now I wish I had a touchscreen.
Fair enough, perhaps some people might be fine with it, but I woulnd't even consider recommending it to family or friends, because I know there would be a lot of confused frustrated people asking me for help.
