I never liked Opera Widgets too much. I tried them a couple of years ago, but I never saw the point. I even tried the games, but they performed so ridiculously poorly that I just gave up. What did I need them for?
Around one year ago, however, I found the first useful widget, a kind of simple “monitor” for the Continuous Integration server run for some project. It was really simple and actually useful (basically, a big window that is either green or red). Shortly after, someone pointed me at a “random lolcat” widget (best widget ever, I say; unfortunately is not public), so I started to wonder if I was wrong and widgets were maybe useful after all.
Since then, I have found another widget that I find very handy, the Twitter widget, and I even realised that the performance problems were something of the past, so I could consider trying a couple of games. And, alas, it turns out that there are at least two games worth trying: Bubbles and my favourite, Ninja Ropes Extreme.
So give them a try, you might be surprised :-)
