Why be incompatible with the majority of Windows installations?
I.e. If you really want to up security from 1.0 (not adverse to that),
then why not go to 2.1 as used by Win7? Win7 is still in support
from MS -- and they haven't indicated a need to upgrade to 3.x for
security reasons. 3.x may have new security features, no argument, but
that doesn't mean 2.1, is insecure.

But does it have to jump to 3? I.e. Why not go a more middle
route of 2.1 -- as it is still security-supported by MS. Ideally
MS would find some bug in 2.1 and allow 3.x to be an upgrade to Win7,
but until then...
