That's you answer to, "Can I start a poll?"
However, since you already have;
I don't like and don't use IE7 except when I have to, eg the odd web site that still refuses to acknowledge the existence of other browsers, or if ever I need to visit Windows Update, (which I haven't needed to for a while). I didn't like IE6 that much and used it about as much as I am using IE7.
That said, I am one of the people who believe it is important to keep up to date with Windows Updates from a security point of view. I know many argue that Microsoft are to blame for all the bad issues with the internet nowadays and although I don't necessarily subscribe to that view, I do recognize that Microsoft are continuously updating its software to combat security problems. Hence I keep Windows as up to date as possible, and since IE is integrated so completely into Windows, I keep that updated as well.
There is one thing I like about IE7, the new tabbed windows options. But since Firefox has had that for centuries I think Microsoft missed the boat with that feature.
Why did you "upgrade" (HA!) to IE-7?
I've been doing computers since I wrote RPG and FORTRAN for the IBM 360 so I know a little something about the subject. Putting a punch card in the IBM collator just a little sideways just to see what would happen is fun. The results are not. But the punched holes make great confetti.
I have tried IE-7 and I honestly cannot see any benefit. Is there something I'm missing?
