I've been using the Bing desktop for quite a while now (pretty soon after it came it if I recall, which I have no idea when). I really like the bing desktop as it adds a new (and usually very cool desktop) every day. I've definitely had a few people comment on it (in a positive way). The Bing tool bar that comes with it...'eh, it's out of the way. Out of sight, out of mind. I always saw the update in my Windows update and assumed it was there because I actually have it installed. Not cool Microsoft if you're trying to push it on people who DON'T have it installed.
