I wouldn't advise anyone to buy this kind of device. That's a given that it's not for me, but really, if I want to have peace of mind, I wouldn't trust any person I know with this. It's a recipe for disaster when it becomes unbearably slow or when anything fails in it.
They're aiming for the MacBook Neo, that's obvious. But at least the MacBook Neo looks like it's a trustworthy device. One that you know will keep on working. Hell, even Apple made a device with replaceable parts (even if they're Apple parts, expensive, etc. but you can advise someone to get it fixed in a repair shop).
Nah, really, the one thing I value most about a computer is trust. Trust that I'm not becoming the repair guy. And for the moment, Microsoft doesn't deliver trust.
