Slowest commonly used browser?
Hmm, I used Safari 5 the other day on this MacBook (on which I usually use Firefox 4.0 beta), and Safari seemed hugely slower than Firefox to me. Really sluggish. Couldn't stand it. So I looked to see how it is supposed to compare. (Incidentally, I've found IE8 to be all but unusable too due to similar sloth, on a recentish Windows notebook which runs FF well.)
