I somehow have a strong feeling that when the hardware is available there will be a huge box of surprises.
Both the UEFI spec and Microsoft's hardware requirements look good on paper, but I already know some HP BIOSes, EFI ones, that did not quite implement the standard, or rather implemented some "additional features". That did make booting almost anything other than preinstalled problematic - there were workarounds for that, but anything short of wiping the whole drive for a fake container partition did not have a chance to boot. On laptops.

We'll see I guess.
