If you're just browsing the net, and have the time and interest in reading another article comparing browsers, read here. I read the article, but it didn't give me any reason to switch from my favorite browser -- Chrome. I really appreciate and like the many features and extensions available on Chrome (running Flash in a Sandbox is a good one), but I suspect it may use the most memory when it's running. The article didn't discuss that aspect of browsers.
One browser that I'll keep my eye on is Opera, when it is available with a built-in VPN. This could be handy to use when one is traveling and using public wifi. Right now it is still being tested in developer mode. Article here.
