I also start by coding with a recent browser but refrain from doing a 'pixel perfect' layout coding. I go for a mostly Responsive design. I DO NOT offer a mobile version for the 8+ year old cell phones with <300 pixel screens.
I do EVENTUALLY view all sites on IE6/IE7/IE8/IE9 but only make SLIGHT changes to address major forms of visually disruptive behavior like overlap, items popping out of intended flow, etc. I do use CSS to turn off image borders & outlines when used in A tags but I DO NOT have a separate style sheet for any version of IE.
Respect! In my humble opinion, that's how it should be done.
