Hello everyone this is my first post here. I have no idea about e readers at all. I've used lcd all my life. Now my eyes are sunken with dark circles and blurred vision for faraway objects. Doctor suggested me to be away from screen for 6 months at least. I don't watch tv at all just reading and note taking stuff on lcd devices. I recently came across e readers but I have no idea how to choose one?
I want an e reader with note taking(stylus)
and Wikipedia browsing mainly. though I also read pdf files given by the teachers but heavy note taking and drawing is my preference. I don't want an lcd one just something that doesn't hurt my eyes. Also is there any android based reader that allows me to install apps?

Price is a huge concern. My country applies huge taxes. A nexus 5 is 550$ and I phone is 1200$:'(
thank you
