I'm currently re-reading the whole of the Discworld collection on Kindle. I used to have, that rare thing, a complete collection of Discworld titles on dead tree unscathed by a single Pratchett signature. But household space limits dictated a move to bits rather than books.

When I finished "Thief of Time", I found that the next tome was unavailable on Kindle as a real ebook. Instead, it was PDF which was inadequate on eInk and pretty hostile on a tablet.

So I've had to switch back to traditional media to fully appreciate Paul Kidby's artwork.
