Do all of those render identically on Mac OS X, or are the colour fringes different for different i's? They render differently on Windows with DirectWrite. If they render differently then you know you support sub-pixel positioning. (I can't claim the inverse, of course.)
> b) the fact the rising DPIs have been on the cards for a long time and are now arriving, making cleartype technology, and the aesthetic philosophy behind it, basically redundant.
How is this so? As DPI goes to infinity, both ClearType and Quartz will look exactly like they would look in print.
Seems like you're still missing the point. You'll see the colour fringes with ClearType too. Here's a test:
iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
