Justin,
...doesn't preview content 'below the fold'...doesn't let you preview behaviour of pseudo classes or the behaviour of JavaScript...doesn't allow the tester to play with various user preferences, system preferences, and things like increasing or decreasing font sizes...
True it's not without limitations, but it's an amazingly useful tool allowing you to preview your layout across multiple browsers and platforms.
I don't have a mindset of pixel perfect at all, but I do care about accessibility. Forget about design for a second here -- the hard fact remains that there are far too many bugs in today's common browsers (IE5.5 being my pet hate) to assume that "standards compliant = accessible".
I'm glad you agree with me on this. The hard fact that is if you build complex designs they will render differently across browsers.
