My arguments trumped yours. No reason to adjust them in the slightest.
When ? We essentially pointed you to all the competiting offerings on the market, their prices and specifications and showed you how Apple's pricing is pretty much competitive to these with the added value Apple throws in.
I don't seem where you made a counter argument to that. Are you still thinking a 27" TN panel 1920x1080 monitor is equivalent to the 1440p LED IPS ATD with FW, GbE, webcam/speakers and daisy chaining capability ?
Apple's ATD is not priced "stratospherically" compared to its real competition, the IPS/PLS 1440p 27" Monitors out there.
