Yes, the reboots are quite annoying on KOReader because it saves progress every 15 mins, so you lose your highlights and notes and progress of the last 15m whenever there’s a reboot. Seems to happen especially when changing frontlight settings. I suppose you could set KOReader to write everything instantly to the internal memory and then replace the SD card once it wears out, which is a huge bonus of the Libra 2. I was tempted, but efficiency is important for me.
Say, say, what’s this special?
