Wow! I’m miffed. I just purchased this, and now it’s abandoned. I’m torn as to whether I should continue using Sparrow, or not.
It’s not all bad news. Part of my motivation for using Sparrow was that the native Mail app in OS X, after the Lion upgrade, was a massive memory hog, and slowed down my entire computer. After the Mountain Lion upgrade, Mail seems to have slimmed down a ton. Performance is no longer such an issue… so far.

I thought I’d try and do this on day one, Thursday, 25 July, 2012, just for something to do. I’ve always waited a few days before doing OS X upgrades to give others a chance to find the pitfalls for me. This time I thought I’d take point.

Mid-morning I tried to access the upgrade from the App Store, and was greeted by a failure message followed by a second message explaining that the service was unavailable, and I should try again later. I figured this might happen, so I wasn’t at all perturbed. I tried periodically for the rest of the day until I finally got a successful connection mid afternoon. I hit the Caffeine icon in my menu bar just in case, and went off to do some other stuff. The download, which initially predicted 34 minutes, took a couple of hours. Still, I expected this, so really no disappointment. After the initial download some scripts ran, there was at least one reboot (not sure… I went out), and everything came back seemingly as before.
