Is that really true in general? I'd say the difference in print start to disappear around 600dpi (dpi/clarity isn't really discernibly different between a 600 dpi print and a 1200dpi print. But up to 600 dpi, I'd say there definitively is a difference)?

Granted, with current technology we have single-coloured pixels, so 300 ppi is really 3-900 dpi (or pixel-parts) -- that might have something to do with it?

The dots in your basic 300dpi monochrome laser printer's output are black or white, but on a 300ppi screen you could antialias with grey pixels (or even subpixels as you note), which can boost perceived smoothness/quality a lot. Figure here conveys a difference between PPI and DPI pretty well: http://en.wikipedia.org/wiki/Dots_per_inch#DPI_or_PPI_in_dig...

Oh, just saw a post about this on another site and noticed it's 231PPI because of the large size. That's a good bit less than the 300PPI on the Nexus 10 that they compare it to in the image on the product page, interestingly. Also south of 1080p and 720p phones, the new Nexus 7 or Kindle Fire, or any of Apple's iPhone/iPad Retina displays.

It's maybe most comparable to the 15" Retina MBP--roughly similar density (220 vs 231), and both are bigger panels you use at a distance.

Just interesting that from a pure spec-wars perspective, raw density isn't one of the dimensions on which the Toughpad is pushing the envelope. Density in its size class, maybe, but not density full-stop.

Depends on how close the page is to your face, and how well you see. The type's size also matters. 7pt type at 300 dpi is not that attractive due to pixelation. However, to even see that, I need my face at 10 inches from the page.
