The only larger than 6" E Ink readers with the new (more contrast) Pearl Screens are the PRS-950 (7") and the Kindle DX (9.7"). The KDX is likely your best choice at present. There are now a few devices with Sipix 9" screens, but they are not commonly available in the US and Sipix has less contrast than even the old Vizplex E Ink screens.

Any new info about the ASUS DR-900/DR-950?
