Not many.
1 - 2008: CyBook Gen3
2 - 2011: Kindle Touch
3 - 2012: Kindle Paperwhite
4 - 2016: Kobo Aura ONE
I sold the Cybook within half a year because none of the books I wanted to buy were available at the time. In 2011 the Touch came out, which made using an e-reader much easier, Calibre had matured more than enough to use, and many books were available now, so I got back into e-reading. The only thing I wanted was a lit screen; so next year, I sold my Touch and bought a Paperwhite. I bought the Aura ONE for the bigger screen. I use this e-reader to this day.
I still have the Paperwhite as a backup. I sideload books onto it if I go somewhere where I don't want to take the Aura. One thing it has going for it is that its battery can be replaced. (Maybe I should do so.)
