Wow guys, what a LOT of information, Thanks!
Found as well some display comparison sheets on wiki, and one interesting Term is the technical name for e-paper: "EPD" or "electrophoretic display" ...lovly, imagine the face of the shop staff having a customer asking for it
Comparison of display technology on Wiki (in General)

Because yesterday I walked into a shop and compared the displays of 3 diffrent Androids, and the one with just a simple,older "Resistive touchscreen" was reeealy bad...it's the kind of devices which have that "milky" surface screen.
The thoughts you guys have about a renaissance of simple low power low price LCDs are worth watching, indeed!
I can imagine the chinese will hopon this probably and produce a lowlow priced one, which would fit into another thread here about "low cost eReaders for the 3rd world" (..hey, I would get one as well for 20 quid or bucks ..we always have to keep in mind that a mobile device can also quickly BREAK outside or while traveling,got stolen, etc

)
