Jacek Wojciechowski's Forum Nokia Blog - How future displays for mobiles may look like?

I also found another interesting solution, but on the contrary - it's not 'rolling type' and this design is bigger - Wibrain's B1 UMPC (specification is impressive: http://aving.net/usa/news/default.asp?mode=read&c_num=54291&C_Code=01&SP_Num=0) - it's like Nokia E70 on steroids

Looks like a scroll. I thought that format went out of fashion style years ago :). Next technological breakthough, wax tablet displays.

Seriously though, I think this format will be very useful for screens connected to mobile devices for education, presentations etc, but not for a mobile's main screen. Maybe we'll have a bus load of people unscrolling their morning paper to read the funny pages.

It looks very good for ebook readers, but for a phone, I don't think you want to have to unroll the screen before being able to see if you have any new messages. I guess having both alternatives in one device might be nice, though.
