For the longest while I wanted a portable e-ink display for outdoor use (just something good enough for terminal, text editing, maybe some light browsing), but sadly nothing ever really materialized. There are larger panels available [1] but require enough low level work that nothing's ever really materialized.

There's one Chinese company that's shipping a 13.3" USB display ($1300 for the first gen [2] or $799 to pre-order a second-gen product [3]) and surprisingly enough, 10" Pixel Qi screens are also being sold, with some support for about $400 [4] or for about $150 from random Chinese retailers. [5]

Currently, the easiest/most cost effective options for getting a large e-ink display showing content are either buying a used 9.7" Kindle DX (around $150-200) and hacking VNC onto it [6] or doing running VNC on the 13.3" Onyx BOOX MAX (~$650, in short supply, it runs Android 4.0 and has wifi, BT and a pressure sensitive touchscreen/stylus so has some potential) [7]
