Overall, it's not really worse than what you'd have with XP...
I'm not a big fan of Vista, but this is definitely not what
people make it to be.

That protection bit isn't what people make it to be either, which is
the whole point.

Quite often, the *real* security issue is that the protection a given feature
*actually* provides by design isn't the security that people *think* it
provides.  For example, some of us may remember a while ago, when there was
a whole flurry of activity regarding TCP sequence numbers and RST packets.

Turned out that in fact, TCP has *always* worked that way, in that an RST
doesn't have to match exactly, it only needs to be inside the window. When
RTT*bandwidth products were low and windows were small, in a 2**32 sequence
space, the distinction between "match" and "within 16K" was easily overlooked.
The community just needed a slap upside the head, because with multi-megabyte
windows on today's high-speed links, the distinction *is* important....
