IE is integrally tied to the Windows OS, which is the weakness that allows the worst of the malaware to access your OS via IE. I don't know hwo far SP2 will go toward fixing this.
2.Tabbed browsing [ Opera can open a new browsing session with all the tabs you had open from your last session]
3. Built-in Pop-up blocker
4.Faster
5. Download Manager
6. Cookie Manager
7. Password Manager
8 Moz/FF or Opera are immune to Hijacking [CWS, IDG, LOP, etc...] as well as attacks that are ActiveX-based
9. Highly customizable via extensions [over 135 available] http://update.mozilla.org/extensions/?application= and themes link is for FF, Opera also has many custom themes available.
10. Supports the Open source community, where some [most ?] of the best work on the web is being done on a daily basis [again Moz/FF here, Opera is $39 US.]

I'm not inherently against Internet Explorer, or even Microsoft, but it looks to me like the only reason they're even thinking of improving IE is because others have built a better, faster, more secure product,and people have been migrating away from IE in droves. I hope IE7 is everything it should be, there are, after all some very talented folks in Redmond. I just think the alternatives are better products, and I imagine that by the time we see the next-gen IE, Moz/FF/Opera will have moved that much further ahead.
Sorry about the rant, but you asked
