If Microsoft really wants to impress me with a new feature in IE 7 then why don't they start by making it compatible with the Internet standards which were laid out years ago. You know the standards that every other browser follows. Do they really think I can be easily excited by features I'm already using in Safari, FireFox and iCal right now? (tabs, RSS and ICS). Why would I wait for a promise when I can actually use the technology right now out of the box in OS X?
