While perusing my blog subscriptions last weekend I found a link to something called Microsoft Calculator Plus. Being a recovering calculator geek, I immediately had visions of a really cool customizable scientific, engineering, and programming calculator. ...so much for that dream.
It turns out that it's really just a simple, more attractive replacement for the standard Windows Calculator. The one caveat however is a handy units converter.

If you're looking for an little improvement over the plain calculator, then this may be for you. But if you're looking for the mother of all calculators, don't bother.
I guess I'll just keep buying batteries for my trusty old HP 16C.
