Why would anyone need a full screen calculator on anything except a Windows phone? I have a 13" touchscreen and I can press buttons with my palm. This is the dumbest default calculator ever. If you are going to use a calculator on your desktop you probably want to see the application you are using it with too. The old calculator that was used since Windows 3.0 was fine. Fullscreen impractical for any device except phones.

This simple calculator app has all the features you need. The scientific calculator and converter is extremely useful. The ability to snap it down to 1/4 screen while viewing other apps shows off the best feature of the Surface.

Very easy to work with. After using it for several years it wouldn't work so I uninstalled it and reinstalled it. Works great once more.
