I'm ready. I realise some people aren't, but I'm young with good vision; "microscopic" is exactly what I want. I'm buying the extra pixels so I can fit more on my screen, not so I can fit the same stuff with better-rounded edges.
I'd argue that Unity looks much, much better on high DPI. I run it on an old crappy 1024x768 and a newer 1920x1080 of around the same size, and the icons/launcher actually look sane at almost double the DPI of the older screen. Unity makes the low-DPI computer look (and feel) like a toy, but I like it a lot on my new computer.
I'd agree with you if you're running Gnome 2, or KDE, though.
Well the thing is that most people don't prefer Unity and neither do I. I don't really think that there are so many devs using Unity either.
