While I'll grant you that the coating matters, the differences between IPSes and TNs are far greater than just pixel sharpness at the film level and all of which contribute to picture definition. The difference between an iPod Touch and iPhone 4, for example, is striking and I have myself observed the difference by viewing medical images on both.
I was the one who explained the different technologies to the radiologist after he mentioned it but to him it acted completely as a blind test. He preferred the IPS-based iPad to his workstation TN despite the lower resolution and without any knowledge of LCD technologies.
Edit: To clarify, I am not talking about the dedicated medical workstations. Medical-grade displays are all IPS-based and for a very good reason. I am talking about the personal workstation TNs that doctors have on their desks.
So all you're saying is that a better screen technology is better... No news here, although I wouldn't classify TN as "fuzzy".
