I can’t wait to get a Kobo… but my 10 year old Kindle Paperwhite refuses to die (I just transfer books to it via USB, it’s not been in contact with Amazon for years). I did put an OS on the paperwhite allowing for white text on a black screen and it allowed epubs but it was a bit crashy and needed to be rebooted every now and then and a Kindle reboot takes several minutes. Definitely a Kobo next though…
