I surely hope that Lion does not mean a locked OS like the iPhone and iPad. That would be bad news for everyone that has multiple uses for their Mac intel computer. I think the 30% commission for the MApp store is steep, especially for specialty software makers. A $500 application in the MApp store would generate a $150 commission for Apple which would lead to higher costs on software. Also will Lion require only software that is pre-approved by Apple and will that be the only place you can install software from?
