I was making a light-hearted snipe at Greebo, who said in the other thread that he didn't see the point of such high DPI monitors. I am genuinely looking forward to higher DPI monitors becoming available in the near future. I have previously owned a 2560 x 1600 panel of 30" which I really liked. The only reason I moved from it was because I was an avid gamer back then, and even two 8800GTXs weren't up to the task of pushing that many pixels. The thing that stops me from getting another one is the knowledge that much higher resolution panels will be available soon - I just hope that 4k panels become available before my existing monitors die.
I can sort of understand your gripe against such monitors, but with proper OS-level DPI scaling the issue of font sizes goes away, and then you get to enjoy the jaggy-free experience in full.
