Well, for the last few months I've been using Opera as my primary web browser and E-Mail clien, and now here are my thoughts.

The Good: Opera's UI can be much, much more attractive than Firefox's is. Also, I found that I liked Opera's built-in RSS aggregator better than Firefox's. Furthermore, when browsing image galleries online, I could use the fast-forward and rewind buttons to easily browse the images.

The Bad: It's a resource hog. Furthermore, while the spam did a good job catching the spam, you still see the spam in your recieved box, as well as your unread folder.

The Ugly: Opera does not play well with others. After I had decided that I was done with Opera, I attempted to export my bookmarks and months of E-Mail from Opera. Much to my annoyance, I was unable to export my E-Mail, and found exporting my bookmarks to be problematic. Major Buzz-kill right there.

In conclusion, I'd reccomend sticking with Firefox. The memory, e-mail, and import-export issues just were enough of a problem to go back to Firefox to say. Now, as Opera's free verision now is, completly free, I would reccomend giving it a shot if you haven't before, just to see how you like it.
