Was thinking about using the Comixology app, is it available for the UK? And whats it like reading them on an iPod/iPhone? I would imagine it would be quite difficult on such a small screen.
You can view your comics in panel mode, and tapping/swiping moves you along to the next panel. In that way the panel fits the screen and you are not constantly zooming in and out. The display on the iPod/iPhone is very good so comics look nice.
