Too soon to say - those where first results (about par with "it boots"). ;)

Will be poking at this machine more today -

I do not have a copy of any proprietary operating system to compare with
on this machine.

You could use the search features of this forum:
http://forum.netbookuser.com/index.php
to look for windows problem reports/discussions.

That forum was active since the machine was announced and included
members from Everex.  If there where windows problems, they are
in there somewhere.
