As far back as 2002, there were 22" monitors out by IBM and Viewsonic, with a native resolution of 3840x2400, or around 200 Pixels Per Inch (same PPI as the new Nano). Since then, it seems that not much has happened on the high resolution monitor front, it even seems like both IBM and Viewsonic have discontinued theirs. Does anyone know if any manufacturer is making larger than 20" panels with more than the usual 100 PPI? After getting used to reading on my crisp 17" 117 PPI MacBook Pro, my 23" 100 PPI ACD looks pretty fuzzy. I would love to have a 23" or 30" monitor with that pixel density as well. The high-resolution 17" screen for the MacBook Pro even has 133 PPI. So for the next 30" ACD, I really hope for a slightly higher resolution than 2560x1600, to make it crisper. It doesn't have to be all the way up to 3840x2400.
