I use Sparrow's iOS mail client and I love it; it lets me toggle seamlessly between work and personal email accounts, and makes it easy to obsessively archive messages in my ongoing pursuit of the ever elusive inbox zero.

But now everything is probably ruined, except gmail, I guess. Cnet reports:

Google has acquired e-mail software startup Sparrow in a move that brings its team to work on Google's Gmail product.

Sparrow's chief executive Dom Leca announced the news on the company's site and Twitter account this morning, as well as in an e-mail to existing Sparrow users.

Leca says that the company will continue to make Sparrow available, and keep it up and running with support, though he did not offer any details about the addition of any new features in the months ahead.
