Actually most of the heated discussion is caused by a huge hole in Apple products line; a headless machine that is less expensive and smaller than Mac Pro. If you rule out iMac (do not want integrated screen) and Mac Pro (too expensive, too high power consumption, too large and so on) your only choice is Mac Mini. It is a niche product that does not match most people requirements. Since it does not match they complain. In other words many people need product B but the only choices are A and C. Neither one of A and C matches their requirements.
I cannot understand why Apple can produce every possible combination of iPod, including models that seem to be similar but cannot create a Mac that is smaller, cheaper version of Mac Pro. This was rehashed hundreds of times in this forum and others. Unfortunately Apple never addressed this market. It is a brilliant company but very a arrogant one. The needs of customers are not taken into consideration for the products development. They know better than customers themselves what is needed. If your needs match what Apple came up with you are in luck, if not you are screwed and destined to go to dreadful PC land.
