Windows Calculator is a joke -- who wants to use the on-screen version of a $5 dollar calculator. Most replacements are far more powerful but kind the "lots of buttons" calculator interface.

Google leaves programs in "beta" long after most companies would have released a "release" version. In the case of the Google Earth beta, Google is just released its 4th major release and the program is still considered "beta." In case you are one of the rare people who has never heard of Google Earth, this program allows you to view Earth from space and then get very close to just about anywhere on the planet via satellite images. It's a lot of fun to play with and even has real world uses.
