Phil Libin (CEO of Evernote) – Four Lessons From Evernote’s First Week On The Mac App Store:

"If Evernote’s desktop clients were written in Adobe AIR, I’d be worried right now. The immediate popularity of the Mac App Store, and the iPhone App Store before it, reinforces my belief that in a world of infinite software choice, people gravitate towards the products with the best overall user experience. It’s very hard for something developed in a cross-platform, lowest-common-denominator technology to provide as nice an experience as a similar native app.

As the CEO of a software company, I wish this weren’t true. I’d love to build one version of our App that could work everywhere. Instead, we develop separate native versions for Windows, Mac, Desktop Web, iOS, Android, BlackBerry, HP WebOS and (coming soon) Windows Phone 7. We do it because the results are better and, frankly, that’s all-important."
