I used Opera when it was the only browser with tabs and when it was handily faster than IE or Mozilla. Opera still has the best user interface IMHO. The thing is that every new version adds more gee-whiz features but is less robust. While Opera is nice it crashes and hangs too much for me now. I found that now that many of its features have been incorporated into firefox and even IE that I use Opera less and less. I don't even have Opera installed on all my computers any more.
I like it, and use both Opera and Google Chrome regularly. I like them both.
An advantage of Opera is its "Speed Dial" that gives very convenient access to your favourite sites and it can handle a huge number of open tabs very efficiently. I also prefer the way you control the "Internet options" (like cookie, pop-ups and add-in handling etc) in Opera.
IdK about using opera on the computer. but i used it on my phone for the mobile web browser and it was great, but now i have bolt web browser on my phone and its waaaaaay better than opera. in my opinion. (:

Use Google Chrome, it beasts all other browsers.
