The Windows computer I have to use at work takes over ten seconds to open the calculator. It literally is faster to type the calculation I want into a search engine and get the results back over the network.

The new calculator even manages to screw up basic input. The old calculator accepted both commas and periods as decimal separator inputs. It just worked no matter what I typed in. The new calculator has some sort of "clever" localization where my inputs change depending on the language of the operating system. My language uses commas so of course it only accepts those. Infuriating. Hope whoever coded this is enjoying their promotion.
