The Mac App Store launched today to much fanfare, bringing with it the first apps available for purchase and download. There is fair amount of launch day content (although Espresso is currently absent, which will be my first purchase) including Twitter for Mac.

It’s not all great though, as it turns out there is no way to transfer an app purchase to the new app store, meaning you miss out on auto updates and other benefits unless you repurchase the license. So the iLife 11 upgrade I bought in October will have to stay in application limbo until the next paid-for upgrade.

As has become the usual from Apple, bittersweet.
