Apple have for a long time now been heading down the mass market road, professional tools where people use a computer for serious work with complex applications is not what Apple is interested in any more. Such markets require a lot of investment to provide features for a relatively small market, many of the features missing from final cut pro X for example are probably only really used by a few thousand serious professionals worldwide. Apple has clearly decided that selling to a wider audience is more profitable. The more mass market tools they can get on their platforms the more hardware they will sell. So if Final Cut X is seen as an almost professional video editing system for a cheap price they could sell a million more macs, where as the perfect pro suite might net them a few thousand top end systems. A million more consumer level mac sales are far more valuable to them as their economies of scale go up, they can push the component prices down and make higher profits on every mac sold.
OSX Lion has been dumbing down with features like versions and local snapshots that can't be turned off, I have stayed with snow leopard because Lion spends to much time trying to force me to do something its way rather then letting me choose how I want to work.
Finally Apple stumbled across the app store model after the release of the iPhone, consumers pushed to install their own apps on the device and Apple reluctantly created the walled garden that requires you to pay to play and takes a cut from every app sold. What use is selling 1000 copies of Autocad via the app store even with a $300 commission when you can push out 5 million copies of some silly game that will get forgotten about in 6 months time and the next craze comes along and sells another 5 million copies.
Apple is all about increasing market share, get as much hardware out here as possible to fuel the app store model and get as many mass market titles in the app store as they can to further extend the captive market for even more apps from the app store.
