Ok thanks for the replies.
I'll stick with my PW and PW2 then.
I have to many epubs to buy a Voyage.
I's a shame that PW and PW2 have no physical buttons though.
I tried an android eink reader (Icarus Illumina) but it's really not smooth.
I tried to go back to the kindle Keyboard that had physical buttons but I messed the backlight and the speed too much
Well if you guys need help, I'm still here
