I used to have a K2, but upgraded to a DX (or rather was gifted one). It's just barely big enough to read Academic two-column papers without making your eyes bleed, and the native PDF support works great, which is fantastic. But regardless, the thing is still useless in a live classroom discussion environment where you need to page faster than 0.2 pages per second.
