Well, there's the enTourage eDGe. However, the 9.7" e-ink screen is mated with a ten-inch LCD Android tablet and weighs as much as the Asus 10-inch tablet netbook (about three pounds).
Not something I'd recommend for just reading. (I use my 8.1" iRex for that.)
There's also the 10.2" e-ink iRex DR1000 if the price tag doesn't send you into shock. Its firmware (in beta now) is being synchronized with the DR800, so it'll be basically a bigger DR800.
