Possibly. I've seen relatively impressive displays on palmtop
computers (the one I saw had radios in it and was being sold as a
phone). Going external will be difficult because of the bandwidth
needed for that kind of resolution at desktop sizes.

Nice. If I didn't (a) expect the hardware to be undocumented, (b)
dislike supporting Apple, and (c) dislike the mechanical flimsiness
that goes with the current drive to thinner and thinner laptops, I'd be
tempted to get one.

3840x2160 or some such? With a pixel clock of almost half a gigahertz
(at 60Hz vertical), I suspect the interconnect is a major reason
they're not wider-spread. (Also not of much use to me, though that's
nothing new; (a) my desktop doesn't have anything like the framebuffer
RAM[%] or pixel clock rate for that and (b) almost certainly doesn't
have an electrically compatible video signal interface.)
[%] Well, at 2bpp it would, but I don't think its pixel data path can
However, 185dpi isn't all that high-res. It's definitely getting into
medium-res, but 300dpi laser printers taught me I can see 1/300" under
many circumstances, and I don't consider it really high-res until I
can't see one-pixel differences under pretty much any circumstances.
(My idea of high-res is something like a 2400dpi digital typesetter.)
