Im also curious to watch which FireFox etc functions M$ takes and places them into their browser....
Careful. Firefox got tabbed browsing from Mozilla, which got it from Opera, which got it from Excel, which got it from UNIX tabbed terminals. Firefox got plugin capability from Kmelon, which got it from gaim, which got it from a trillian other orignations.

Don't think firefox is origonal on their ideas, in the same way that IE7 won't be either.

but im looking forward to seeing what M$ thinks it takes to make "virus, scam and phishing" proof web browser....
Careful there too. They are fully aware that it isn't 100% foolproof, just as you and I are. They are talking about implimenting things to help prevent and stop virus spreading/scamming/phishing. They are not talking about putting and end to something that everyone one of us knows there will never be an end to, in any operating system.
