"For starters it uses an ultra-sensitive 2,540 dpi touchscreen (0.01mm dot pitch). That’s currently unparalleled in the tablet space, and it needs this level of sensitivity in order to function as a notepad and effectively record the tiniest details in handwritten notes. While handwriting can be slower than typing long reams of text, it gives much greater freedom than a laptop to use personal shorthand and entire document freedom, as well as opens up the possibility to easily add mathematical or scientific formula. This makes business meetings or lecture note taking much easier.<p>ASUS docs state the touchscreen also has 256 levels of sensitivity so it knows how hard you’re pressing, which can mean the difference between a dot, a dash and a stroke, and even though the EA800 only has a monochrome display it features 64 grey levels between black and white for at least some measurable level of contrast. The best example is probably to try reading manga and comics on it, we’d imagine."[1]<p>[1] <a href="http://techinstyle.tv/products/can-asus-eee-note-ea800-reinvent-the-digital-notepad/" rel="nofollow">http://techinstyle.tv/products/can-asus-eee-note-ea800-reinv...</a><p>Also see <a href="http://www.mobilityfeeds.com/mobility-feed/2011/02/asus-launches-the-eee-note-ea800-ereader-tablet-touch-screen-touchscreen.html" rel="nofollow">http://www.mobilityfeeds.com/mobility-feed/2011/02/asus-laun...</a><p>tl;dr; It appears to have a very high DPI for a tablet display along with 256 different levels of pressure detection.
