Okay ill give you points because I never heard of Xteink X3or the open-source CrossPoint. I have a Kobo reader/pen note taker and a Kobo ereader (somewhere) one is too large and one is just meh. Im going to try one of these but it would have been easier to pick something if you actually said HOW DOES IT WORK OUT OF THE BOX AS AN ACTUAL EREADER!
