In my "Is there a future for Mac software?" post I postulated:
"I sometimes sit and wonder what sort of applications could have been made for the Macintosh if, say, Apple had opened up an App Store that supported iPhone, iPad, and Mac? Would the river of money have been split into three smaller tributaries? Would people flock to the Mac the same way they have iPhone and now iPad? Arguably the main reasons people buy iPhones and iPads is the ease of finding/installing software and content. Imagine if things were that easy on the Mac. And imagine if developers were excited to build applications for the Mac again!"
Well, I needn't wonder anymore. In answer to an email asking about a Mac App Store Steve Jobs has replied "Nope".
I know developers wouldn't want the closed nature of the current App Store in any type of Mac App Store but that doesn't mean they wouldn't be in favor of a Mac App Store to help promote/sell their applications.
Oh well, software on the Mac will have to find another way to survive.
