Opera 7.5 is out !
Still a preview, but this is something that I've waited a long time for!
Couple of notes:
* tabs, or "Windows" as they name it - not quite what you are used to, but it might work over time ( and CTRL+T opens up bookmarks, not a page )
* Change styles - excellent to test for text reader etc.
* speed: it's fast!!
* Nice panels - just the placement that I'm a bit annoyed with
* CSS rendering is good so far - http://www.csszengarden.com/ renders as it should
Just got this down so I have to play with it a bit more, but overall: nice browser, but I still prefer FireFox....
