I'm keeping my not-sure-how-old iPad 5 around specifically because it's the device form factor to read pdfs.
However it does sound handy, I kinda want a dedicated tablet for sheet music.
Would I prefer more content to be reflowable etc.? Yes - but with a tablet it isn't strictly necessary, just nice to have.

This is awkward, that's the issue I mentioned above, how annoying is to have to do that if you're reading for a 30-60 minute session.
