I do love my Opera browser. It is indeed fast and NOT at all a ram hog like Safari. I'd love to use Safari all the time cuzz of its elegance and sleekness but it's a huge master RAM hog - within 1 h of heavy surfing the RAM it uses jumps to 600+ MB with huge VM page outs thanks to all the Top Sites eye candy and what not cache. I still use Safari and still think it's the best browser for Mac but here comes Opera 10.5 that is at last fully optimized for Mac. After a long time. Just read it on the opera blog: http://my.opera.com/desktopteam/blog/2010/01/20/return-of-hot-chocolate Anyone here using Opera as secondary browser?
