I should add that I'm OK with writing for IE 7 and the fewer IE 6 users there are, the better. My main irritation with IE 7 is that it doesn't run on all platforms and that, thus, given that browsers are all different in how they interpret pages that it's not the ideal browser to target first. Normally I can work around the differences, but if I have to pick to look best, it'll be Firefox, memory leaks and all.
