I can’t see how Internet Explorer 7 is in any way a bad thing. IE badly needs an update, as both Opera and Firefox way outclass it in terms of features.

With a bit of luck this’ll encourage competition, too. Not that IE’s going to catch Opera up any time soon, however. Having used it for a few weeks, I still highly recommend it. I started typing a little review just now, but I’d prefer to do a proper write-up when I have more time. Here’s a screenshot of my current setup:
