From Opera Software:
If you use the web for work and not for entertainment, Opera is by far the best choice you can make. Why? Because you can: open multiple windows without running out of memory open documents in the background without destroying your search engine result listing redirect the output from one window to another toggle images online and per individual window toggle document and user settings add all open documents with just two clicks retrieve all documents in a hotlist folder with just two clicks navigate entirely with the keyboard -- for more speed zoom in and out of the pages and a lot more... Impressive, isn't it? Have a good look at these features again, because you are likely to find them in one of the next versions of our competitors, who are trying hard to match Opera's really useful features.
What's new in this version:
Skins. Flash enabled. New progress display and stop button. Works faster with improved mouse navigation. Improved window handling. More privacy. Updated E-mail client.
