I've spent a little extra time lately playing with Opera. Turns out its a very underrated browser,.. its got some very nice features. Developer tools are pretty good(better than IE I must say, although not quite to par with FireBug). Installing is a piece of cake by just dragging an icon onto your toolbar from the website! Some of the other features I've found useful is Opera's built in BitTorent, the mini view(Shift F11) for testing on small screens like phones, "speed dial" on new tabs, IRC, and even the real-time page search to name a few of my favorites(theres a Lot more). I'll definitely spend a lot more time developing in Opera from now on!
