Hmmm...I'm such a 'tard, lalala, but I just now decided to try Safari 1.3 because slow text in the textbox in Firefox was bugging me (every once in a while, text entry in textboxes becomes painfully slow in FF, for me!). But wowsers, Safari 1.3 is fast.
If only someone would write something à la Tabbrowser Extensions for it. And it does seem to have some reduced compatibility with (probably incorrectly written) webpages such as Friendster.
But, oh yes, fast. And oh, oh, having inline spell-checking back is a nicety.
