Come on, you own an iMac and your asking me what the experience is?
Maybe i've expected too much from you all. I'm used to speaking in an academic setting where I can safely assume that my particular audience has an ability to use some logic and reasoning.

(I kid)
But seriously. The platform that I speak of is the whole of Apple's offerings.
True enough, the hardware that is intergrated into the machine is no different than your standard windows boxes, however I would define the platform as what Apple has laid out.
In a nut shell, alot of the users clammoring for a midrange tower, one that psystar..eh.."offers", are complaining because its simply not the market Apple is in. Apple's offerings are pretty good, in my opinion. Could use a blu-ray drive in my Macbook Pro, but thats besides the point.
Users are looking for something that does not exist (and shouldn't for various reasons). It does not matter what everyone wants, because that is not what the manufacturer is offering. As long as you are in your legal right, if your vehicle does not have an intergrated GPS system, then the platform that the manufacturer has defined will not work for you. Plain and Simple. You can either fudge that requirement, modify the vehicle to your specs, or move along like a good peon.
However, when strictly forbidden by the owner of the work, you may not modify to your hearts content. Software has been restricted in this way because of its relatively easy nature to rip off, and provisions have been put in place to protect IP in the industry, an industry that was once a wild wild west of ideas being stolen , even when one went through the proper precautions to protect their work.
Apple's platform has been defined for us. As it stands, if you want a Mac, or OSX, or logic, or Final Cut Pro, you can have Logic, with a Mac and OSX, or Final Cut Pro, with a Mac and OSX. Heck, you can even get a Mac...with OSX. Apple doesn't even care if you run Windows or not, and aid the user in doing so. You are not at liberty to change whatever you wish in an opportunistic fashion , as these individuals have done.
If you don't like anything about the system(platform) that Apple has laid out, it is your moral and legal right as a citizen with a brain to choose another option. Done.
