"According to the report, Apple is still deciding whether to offer a retail box version of iWork '11 or if it will be available exclusively through the Mac App Store."
I'm sorry for being Mr. Glass half empty, but this would really scare me. If the are planning to offer it exclusively in the store, more and more developers would follow suit. And.. I don't know, for me it would be a step closer into making the Mac App Store the only way of installing apps.
I know the store is hugely beneficial to developers and most people. I can't deny how big the exposure is. But I'm just concerned how restrictive and iOS-like the future could be. In a bad way. =S
