I haven't seen it and you haven't seen it. What's your source? Are you
talking about the version in the Windows-only trials during the next
month or two?

Because Microsoft and OLPC announced dual-boot. Because Microsoft
can't buy XOs for resale, and OLPC has no intention of shipping
Windows-only XOs. Egypt wants dual-boot.

OK, so Microsoft could arrange to wipe out Linux after delivery. Then
what? Do you think that the world will stand still for that kind of
overt sabotage? I can't imagine OLPC signing a contract that would
allow it. I gather that you can. You're on crack, Albert.

Sources, please. Who says what the dual-boot architecture will be? If
you won't be able to run Linux after the first time you run Windows,
as you seem to allege, in what sense is this dual-booting? Are Mitch
and Scott such technical idiots that they wouldn't spot this?

Albert, I'm not talking to you any more until you start making sense.
Linux BIOS never booted any Windows other than 2000 (with ADLO), and
EFI isn't Open Source.
