1)don't see why you would want to. The default configuration is fine.
2)Not really a necessity. also note that IE7Pro is a third party tool as well as Ad-Block.
3)Opera doesn't either but a little bit more functionality in Safari would be nice(out of the box that is)
4)Bookmarks are a thing of the past
. Opera's startbar wins
5)i kind of agree with you there. When i used Safari, it didn't open any links in a new tab for some reason. When i forcefully open them in new tabs, it just doesn't feel right. At least they're better than IE7's tabs...
6)Safari was faster for me.
1) I like to tinker that's why I have 6 browsers.
2) No browser comes with everything so addons are nice to personalize the browser.
3) Opera does not support addons but there are hundreds of "custom buttons" that really add to the features of Opera. Aspell also works well in Opera so I have a good spell checker.
4) I don't get what you mean about Opera's start bar. I use side bars for book marks. Opera lets me put it on the right as does the Firefox addon All In One Side Bar.
5) We are in agreement
6) All my browsers are fast on cable. It's just that Safari is making a big deal about how much faster it is when at best it was equal and in the case of IE7 it was actually slower.
