Damn, this baby is fast! I mean noticeably faster than Safari 3.12, faster than Firefox 3, faster than Opera 9.5.2, faster than OmniWeb 5.8 sneaky peak -- plus, it's Webkit, so I can use the Services menu with Devonthink Pro, MacJournal, and every other Service friendly app I use every day. Only the fact that I use add-ons Saft and SafariStand with Safari makes Safari a slightly more useful browser for me.
iCab is also hugely customizable, and has lots of neat features, for example: iCab sends e-mail and emails pages, can speak the text on most web pages, has a very nifty Session manager built in, and has a lot of damn cool contextual menu items: back/forward/show source, download, check syntax, open in new window/tab, add url to bookmarks, open image externally, as well as some great submenus such as show all links. These are only a few of the cool features.
Some years ago, I paid for OmniWeb, and I've always been glad I did, as it's given me good service over the years as an alternative to Safari and Firefox. But I have to say I'm seriously thinking of sending my bucks to iCab to thank them for making such a great, FAST browser (even though the free version use is totally unobtrusive). It's that good.
