What is Apple up to ?

Adobe Premiere ( video editing software) has stopped producing for MAC. Internet Explorer has done the same for Mac last month.

Apple has launched products which directly compete with Adobe's Premiere and Microsoft's IE. Did this prompt the move ? Apple hasn't built its version of Microsoft Office, but reports say it is working on it.

What is Apple trying to do ?

Apple has the advantage(?) of developing both the OS and the hardware and so could build more tightly coupled hardware support into the OS. By developing everything itself,it can deliver a great user experience.
But will it work ? My gut feel says NO ! There is only a limited set of stuff a company , however great) can do and do well.
