Since the App Store launch, more than half of Evernote’s new users across all platforms are coming from the Mac. In fact, between Mac App Store launch and midnight on January 7th, Evernote saw 90,000 client downloads across both new and existing users.
It does not matter how “free” an app is if it is difficult to find or no one has even heard of it. Cost also does not matter if it is difficult to install. I’d be a rich man if I had a dollar for every person I encounter in my consulting business that downloaded a .DMG and did not know how to “install” the app from there. Or hit the download link on a web page and had no idea where the file actually went after that (changing the default from “Desktop” to “Downloads” did these folks no further favors). I would be willing to bet that 90% of those 90,000 that downloaded Evernote the first day the Mac App Store was open fit into one of those categories.
