I recently downloaded IE 7 Beta and I must say it's impressive; it has the features that made Firefox make IE 6 look like garbage. Tabbed browsing more than anything is a feature I've learned that I cannot live without; especially during draft season when I have multiple pages that I reference at the same time (along with a window for the cafe of course). Seriously, I went to work once and they still had IE 6 and I found that I was not only frustrated, but my productivity sucked.
But, IE 7 lacks a key feature that I utilize in firefox daily, and that is the Find feature; that is, in firefox, the find function is actually on bar right above the status bar that actually finds the words as you type. Microsoft is still using that horribly antiquated "find window" that pops up and only allows you to search for one word at a time. I hate it. So, Firefox still wins.
As for viewing web pages, I say, if people are still using IE... good riddance.
