Sparrow for Windows
/Ellis Hamburger on Sparrow for Windows:
To sum it up, Sparrow for Windows never existed.
I recently accepted a new position. This jobs required me to use a Windows machine and let me tell you… none of the awesome software I use daily exists for Windows. That includes Sparrow, Tweetbot, Reeder, Pages, Numbers, Keynote, Pixelmator, Aperture, Fantastical, Cobook, Bettertouchtool, and (to a lesser extent) Garageband. And the Windows alternatives (where they even exist) cost hundreds of dollars more than I paid for the OS X versions I use daily.
I now have two computers for work. The MacBook I use for everything and the HP I use when absolutely necessary.
