I thought I read somewhere that Qubes is moving to hardware-enabled virtualization, \
though? Zen laptops were supposed to arrive first half of 2017, but I think they got \
delayed to second half of 2017 now. So yeah, it will be a while until enough people \
have these. But a Qubes/OEM partnership could still make them relevant sooner. I \
don't know if ZEV will be in all consumer chips, but considering SGX is in Skylake+ \
now, I would hope so. AMD does seem to target this at "cloud companies" in their \
paper, though...I'm sure we'll find out more about it by early next year.
