I didn’t feel very comfortable using Opera. Some of the discomfort would I’m sure go away completely with a little time. There were a few very minor issues, such as this one. The only thing that didn’t seem to work at all for me was Slacker (which I’m currently listening to in Firefox). More on Slacker later, if I can get hit just the right level of slackness to post about it.
Right now, after my brief and unsystematic Operatic browse, I feel more attached to Firefox than before.
