Hi David,
again I am not saying it was making me long to read on the PB360

but it was perfectly fit for the purpose - you could work on the go with it, and I think the render has a lot to do with it. Never used reflow, but for instance pocketbook allows you to zoom by column, which magnifies the thing enormously (well, a certain percentage

)
I was simply trying to make the point that if the readers (and the software!) are well designed, even smaller screens will be acceptable - or maybe I have a low bar (though Kobo does fall below that one)

).
I would have bought a Glo already had it not been for the poor pdf rendering - but I just find the Pocketbook Touch too large to be portable, so I may as well stick to the larger reader I've already got.
