I’ve been using Tiger for a week now. On the plus side, I love Safari RSS. The neat flip between RSS feeds and websites is superb, as is the facility for tracking the number of new posts in bookmarks. I also adore widgets. Especially the one that tells you what the weather is like and saves you looking out of the window. On the negative side, iChat AV simply doesn’t work anymore – audio chats are dropped with the message “insufficient bandwidth” a problem that is apparently shared with other users. I also dislike the new interface for the mail.app.
