I have said before that, but for Adobe, I would abandon MS Windows. And, even for my own direct needs, I would probably already have plunged off the cliff towards Linux nirvana. The anchor that keeps me firmly tethered in the grasp of Redmond is the need to support designers. If the Creative Suite would play nicely on Ubuntu, I would pretty much force about a half dozen or so artists to take the plunge. But, back to reality. The only option away from Microsoft is Apple.
Apple has always been a non-starter for me. Perhaps unduly biased by a father who insisted on building his own computers - literally transistor by transistor in 70's and 80's - the early Apple offerings were considered "toys". That probably wasn't fair, but what might have been a hard-to-justify historical bias has instead become healthy fear of a company that would control its customers instead of serve them (this is done by offering a diminishing pool of seductive choices until one has so much invested into a brand that self-deception is easier than objective decision making - thinking may hurt more, but it's a good pain). Anyway, I don't have a good opinion of Steve Jobs the businessman or Apple the company (Steve Jobs may be a great guy in other arenas). Short story long, jumping to Apple is not likely happen of my own volition.
That said, it'll probably be a moot point soon. As Apple threatens to kill java as a viable application platform on the Mac, one suspects that this will ultimately mean the end of Mac versions of Flash Builder, Flash Catalyst and ColdFusion Builder. The problem is not that Apple will stop supporting Java, but that too much of the Apple platform is hidden from developers:
