Love this amusing concept of drawing upon the designs of operating system calculators from both Windows and OS X widgets as the basis of real world calculators for the (home) office. Designers at Mint Pass created these in what they term a "parody" design, but note they hope one or both companies adopt the idea for promotional use. We certainly second that notion!

As a user of the wireless and compact Apple keyboard, I'd welcome an external calculator in the widget style design, if just for having a notable conversation piece on the desk. And somehow the dimensional version of the Windows calculator extruded out looks much more appealing than it's 2D version. Here's to hoping someone at both Apple and Microsoft see these and make them come to life.
