I may have judged it a little too early...though I still don't like the forward/back buttons demanding a 2-hand grip (or the overall form factor)
You can navigate pretty quickly via the LCD and then "print" to the e-ink for reading. Can do that with just about any kind of viewable content...which is pretty cool actually.
