As part of the recent spate of Apple updates, Steve Jobs gave a presentation on OS X 10.7. Codenamed Lion, it was going to introduce the concept of the iOS app store into the fully-fledged desktop environment. Instead of waiting, however, the Mac App Store will be available in just a couple of months, and Apple is taking applications now.
Whether the Mac App Store can enjoy the same kind of success seen by its mobile brother has yet to be seen. Jobs and co. plan on bringing the same structure and income splits to OS X, too: developers who successfully create an app store entry can look forward to enjoying 70% of the profits each app brings in; Apple will keep 30% for themselves.
The real question here is whether Microsoft will do anything to challenge the move. With 90% of the desktop market, Microsoft may have less to worry about, but they have a lot more to lose, too.
