IBM Prototypes 200 ppi LCD

ghoti writes "IBM has developed a 200 ppi LCD. This is an interesting development, since you can put much more information into the same space - and keep it readable as well. And fonts would look a lot better, too ... So finally, those 32 MB graphics cards will become mainstream ..." Is 200 ppi worth it? It definitely would make anti-aliasing fonts under X less of a priority ;)
