Lol Opera kicks ass. The new 10.53 version is slicker and makes greater use of screen real estate.
Reasons to use Opera:
=> Downloading a large file: While you are still deciding where to put the file, Opera quietly downloads it in the background (to save you time). With IE, the download gets halted until you make your decision.
=> Visual tabs. The old clunky text-only tabs are a thing of the past. Also makes full use of Aero glass effect on Win7.
=> Built-in spell checker. You'd almost think you're using MS Word to surf the web!
=> Fast javascript engine.
=> Favicon "quick link" toolbar instead of clunky text bookmarks.
=> Page find: Dimming of web page in find mode. Green bubble to show you current match, yellow to highlight all matches.
=> Easy access recycle bin to show recently closed tabs.
=> And many more.
