Any kind of bar...
I have phobia towards any kind of bar... even that Adobe Acrobat bar in MS Word gives me the freak.
WHY?
I dunno, seems like all bars do are to advertise a service/take advantage of your desktop/eliminate competition (especially those search engine bars)/ and/or to spy on your online activities.
Yes, Google, I'm sure your bar didn't make u the billionaire that you are now by not cutting out all other search engines.
As for easy access to a web page, I'm sure the favorites menu does nothin. It just sits there looking pretty.
I'm just kidding.
Thumbs up to cluttered desktop. Wait until Windows LongHorn comes out, you can even image the number of helper panes Microsoft will bundle with LongHorn IE.
