Unfortunately, the Sparrow email client will no longer be developed. Sparrow has been my favorite email app ever. I have grown to dislike email in general, and using Sparrow has let me quickly act, archive, delete, etc. And now I guess we will never see Sparrow for iPad.
It got me thinking about how many third party applications I rely upon. And you probably do to. So please support your third-party small software development house.
