This is a really good point. When I've heard others cite their satisfaction level with desktop displays, I ask them to go through an experiment. I'll put aside the size portion of the debate since I can't really fathom how anyone could argue against a desktop display that can fill their entire field of view, assuming such a display were available and economically priced. I think those who argue for small displays on the desktop enjoy being contrarians, and they bring up matters of taste and style (such as "I don't want something so large on my desk."). But in terms of clarity, the argument posed by those satisfied by the status quo usually is composed of these points: 1. Users sit at a distance of 2 to 3 feet from a desktop display. 2. Therefore, high-DPI is not meaningful because the human eye cannot perceive additional clarity at that distance. 3. High-spec IPS LCD screens are good enough. So the experiment is simple enough: 1. Find an iPhone 5+, Galaxy Nexus+, or Lumia 920+. Something with a high-DPI wide contrast-ratio display. Open up a web site or document or whatever. 2. Do the same on your PC. 3. Hold the phone up side by side at the same distance. Zoom the phone's text to match the text size seen on the desktop display. 4. Behold how the phone's display is considerably more readable. For most combinations of phone versus desktop display, the phone's display will be crisper, have better contrast-ratio, and better color accuracy. My Lumia 920 (not even an OLED, just a nice high-DPI IPS display) utterly shames my Dell U3014 IPS desktop LCDs. Reading text rendered with high-DPI, high-quality displays at 2 to 3 feet is an absolute delight. Not only that, you can lean to see greater detail. Yes, 2 to 3 feet is the typical distance, but sometimes I like to get closer to my desktop display to work with fine details. I would pay a steep premium (but obviously I wouldn't break the bank) for a desktop display that matched the clarity of my phone's display. If I could just tug at the edges of my mobile phone and make it magically grow to fit my desktop, I would be so happy.
