Don't listen to these [insert favorite insult here], they're just feeding you a bunch of grumpy speculation about a company that they obviously despise for whatever reason. Plus don't forget that you're in a part of the forum that is the exclusive domain of Windows users right now, so the info you're getting is heavily tilted toward the Mac-hating side.
I think you will be plenty happy with your new Mac Pro (I assume you got at least the 6-core model with a decent amount of RAM and the better GPU). I know plenty of pros around here who use the "canister" Mac Pro to do amazing work and they are all very happy with their computer. Further, Mac OS X is and continues to be a damn solid operating system.
For all the hate against Apple and OS X, just go and hang out on enough PC forums and you'll discover all too quickly that the grass is most definitely not greener on the other side.
Having said that, for my needs I decided that I preferred to build myself a Hackintosh rather than pay about $8k for an equivalent Mac Pro. I'm happy with my decision and it has allowed me to expand my system as I see fit while getting all the benefits of a, for all intents and purposes, Mac. The Hackintosh route isn't for everyone, and in some cases I downright advise against it, but for me, that's what has worked.
