The T220s were very nice monitors, but they just tipped over the 200dpi mark, not the 220+ one.

So basically 15 ppi, then - your comment reads as someone trying to exaggerate the difference - the T220 was 205 ppi, and some of Apple's Retina devices are 221 ppi, a grand difference of merely 7% - well, seven per cent and eleven years.
