I've been using the 3.0 Betas for 6 months now (I registered long ago when iCab was the only decent alternative to IE for "classic" Mac OSes) and I continue to be impressed and pleased by iCab.

Some of the CSS 2 support is truly amazing I wish Safari and Gecko browsers got some of these properties right. If you're viewing a well-written page, all the little things are impressive (LINKs, citation sources, proper quotes). The error check and "smiley face" are invaluable--as well as pointing out how far the web has yet to go to be modestly standards-compliant....

The web is a medium where authors are allowed to *suggest* ways of presentation but users have the final say, and iCab enables this with user-focused features that find the sweet spot between powerful complexity and ease-of-use.

No, it's not perfect (after all, this is a beta), but what browser is...and if you want a browser that passes the Acid2 test, iCab's the only option that's available in an end-user form :-)
