Thanks. Bedtime for me now, but if I decide the Chromebooks are still
a potential option for me, I'll try to find time an opportunity to
look it up (or failing that, maybe dissect one of John Lewis's
prebuilt binaries?) another day.

Already aware of that and I've ruled out everything with vPro/AMT.

I hear you; but I also hear Jonathan Brossard saying that as far as
security goes, "[If you control CPU microcode] updates, you basically

That was my understanding; thank you for confirming it.

I'm no Intel boot-licker - I think the way Intel behaved re: OLPC was
appalling (Intel Classmate, etc) - but I haven't found any suitable
ARM models yet.[1] So it's down to:

- C7/C710;
- Pavilion 14;
- X60(s);
- Yeeloong.

All of which are compromises; and (at least in my view) all of which are votes.

I find that if I mute Stallman, I hear Blank and Brossard ;)

Thanks again :)


[1] Besides, as far as current readily-available laptops are
concerned, it seems that some ARM models are more likely to have
restricted boot than Wintel laptops:
