The PageOne HD looks to be a close relative of the PageOne ereader I reviewed in 2010. It has the same general design and ebook format support, but it also has a new and better screen.
It's using the new flexible 6" screen with resolution on the iriver Story HD (1024x768). It also has 2GB Flash storage, a microSD card slot, but no touchscreen or Wifi. Aside from the screen, this looks to be identical to the one I reviewed 2 years ago, and that makes me wonder what they've been doing all this time.
NextPapyrus used to be an innovative company. I didn't mention them by name, but about a week ago I posted one of their demo videos. Back in 2009 they were doing some neat stuff with animation on E-ink.
Perhaps I shouldn't criticize them, but in the past couple years everyone else has added touchscreens, Wifi, and neat software features. NextPapyrus appears to be standing still.
