Yes, I've seen this too. I'm just now wrapping up a fairly fun
consulting project in which I'm virtualizing a few Linux and SCO
OpenServer machines onto a smaller number of boxes using VMware.
Boot times are a bit quicker.
My "just to boot" comment above, though, wasn't meant to reference
boot times at all, though. I meant "just to come into being".

Feelings?
No, experience. Big difference. Experience with and
knowledge of the past. There is NO RATIONAL REASON why a GUI-based
OS should need more than a billion bytes of memory and a billion-plus
clock cycles per second just to boot. You and I (and many others on
this list) have plenty of examples of machines that do the same thing
with a tiny fraction of those resources.
Minor nit to pick... most of the "billion-plus" cycles per second
spent
on booting are spent waiting on I/O. If you look at the amount of
time
it takes to boot the same OS in a virtualized environment (and thus
has
some reasonable caching going on by the host OS, and emulated hardware
devices), it'll shrink a lot.
And I'm mostly speaking from the experience of running Linux under
Xen,
but even Windows Server 2008 under VirtualBox seemed to yield similar
results, when I set that up for a friend.
