Hey Jolt
No one can fault your logic...

My concern would be that Safari counts for only 1.6% of all users.
IE6, the piece of junk that it is, is still more widely used than IE7.
Firefox has finally overtaken the #1 spot for single version browser. Although if you combined users of IE6 and IE7, explorer still has a wider popularity.
I've always found it interesting that people say 'Standards Compliant' when no 2 single browsers render the same.
One would assume that a 'Standard' would be indocturned across more than just a single browser.
You can find browser statistics here:

Its also difficult to test in both IE6 and IE7 because you cant have both installed on the same machine.
Just more to consider about cross browser compatibility.
Cheers.
