I have both PW3 & Voyage, got them both on sale in Prime deals online. I had a PW1 for years. I like to see devices in stores first. I waited a while till I got the Voyage, mostly because I saw them with blueish screens at first, in Best Buy stores. When I saw one with a white screen, I wanted to buy it. Then I heard about Prime Day coming soon, it was about a week before I saw the Voyage at Best Buy. Since I'm a Prime member I waited to see if it would go on sale too. It did.
I also got the PW3 on a Prime Deal sale a couple months before. I like them both, I use them differently, The Voyage I read at home, the PW3 I take with me outside or traveling. Since the screens look about the same outside without the light on. I use the PW3 light when I'm inside for an appointment or something. It's pretty rugged and I don't worry about it. I recently dropped it face down on pavement ( cover on ) and it was fine. The Voyage has a nicer screen, and I found I like the page press sensors. I like reading it with one hand at night. They are both nice devices. I just use them differently. I would like to see a Oasis one day in the stores too. I'll need to take a road trip to Montreal to see a Kobo Aura One though. It would be a nice trip though, I like Montreal.
I would also like to see a larger Voyage . I hope they keep the Voyages in the line up, like the PaperWhite's.
