I've been a Kindle reader since the first couple of generations and currently have the Oasis 2. I just got a Kobo Aura One the beginning of this week. Here's something I wrote to a friend.
I splurged and bought a Kobo Aura One, hereafter A. I say splurged because this is the larger model they sell and thus also more expensive. I’ve had it for two days so I’m just getting used to it, comparing it to my Kindle Oasis 2, hereafter O.
The A has a more neutral white light to the screen, at least to my eye, while the O is very slightly toward the red side of the spectrum, very slightly.
The O is more even corner to corner but that is only because there is a very small margin around the border of the A that has slight shadowing. It doesn’t affect the text, it’s just there if you look very closely specifically for it.
The A shows more text per screen, maybe 10% more. I can’t get an exact comparison because they handle margins etc. slightly differently. The A also has a more book like rectangular, tall page as opposed to the almost perfectly square O page. That’s a point to the A for me. The actual display area of the A is about 0.4 inch wider and 0.7 inch taller than the O, based on best eyeball guess.
The A seems to be a little more sensitive to touch for page turns than the O. I sometimes, more than I’d like, have to touch the O twice to get the page to turn and once in a while it will only turn by pressing the button.
They are similar in weight, the A being slightly heavier but probably measured only in grams difference and worth it for the added screen space.
Calibre is a whole new universe to me and I know nothing about it yet. I’m getting by with links from Bookbub etc. emails to populate the A. I’m sure in time I’ll get used to it and they tell me I’ll be able to convert and load my O books into the A.
I really like it so far. I don’t think it will completely kick the O to the curb but it’s going to definitely steal a good bit of face time.
