Thanks for the scientific approach
I don't know if it is the fact that I take out my contacts before going to bed, but I was able to read on a shoddy iPhone 3's screen just fine. Before that I read on a Sony-Ericsson P1i which had a really tiny screen and I was fine with that, too.
Or maybe it's my job as a graphic designer that puts my mind at ease when it sees pixels so that my eyes don't try to "sharpen" somethign that cannot be sharpened ?
