I found IE7 fairly annoying at first but once you get into the settings its not so bad. One of the biggest pet peeves of mine is when you open a new tab it has a warning page telling you what you have just done. Duhhhhhhhh.
If you get into the settings that page can go away and it will go straight to the site you were requesting without an additional step telling you that you were trying to open a new tab. You can also disable tabs completely, but I find them useful once you disable the default warnings.
