Ryanair do have an in-flight magazine, and it's quite good (in my opinion).
As to paying for the exit row seats... this would be a disaster for me! I'm tall and use Ryanair a couple of times a month, and can't remember the last time I didn't manage to get one of the overwing seats just by being in the priority boarding queue. Yes, I'm one of those people who leg it to the plane to bag those seats first, but recently I've started to think this isn't necessary as most other people doing the same seem to be heading for the front few rows (to get off first). 15 Euros is a bit steep though... I don't think I'd pay it...
