I travel on low cost carriers on a regular basis between European destinations. Several years ago I bought a Paperwhite, specifically because I was tired of lugging around heavy, space occupying paperbacks, which I often finished enroute, leaving me nothing to read for part of the flight.
If I didn't already have the Paperwhite, I'd be seriously tempted by the Oasis.
I was being a little snarky. All I meant is that the Oasis seems to be a rather premium device compared to a Paperwhite and that doesn't obviously overlap with the market for low-cost airlines. (Though, to be fair, the dynamics on internal European travel are a bit different than the US.)
