My 10" Boox Note 2 works surprisingly well for technical documentation, as a combination of its size, it's high resolution and its ability to set the refresh of the e-ink display to what you need. Want to pan around quickly? Set full-refresh lower, and it will let you pan around and zoom quickly (somewhat messily, of course) and then full refresh when you stop. It's quite remarkable. Expensive devices though.
