I have long been a fan of the Google toolbar for IE, which allows you to enter a search term right in the toolbar, without going to Google first.
Well now there’s Nutshell, which is the same idea, but you can choose to search in Google, IMDB, Amazon, Dictionary.com or Daypop. Cool.
(Bonus geek points if you know which current computer program, eclipsed by its Microsoft rival, was called “Nutshell” when it was first released in 1983.)
