To each their own, but I tried using an iPad as a reader, it just didn't work.
If you are in Europe, why not the new 10" Samsung?
Otherwise, wait for the Asus Tablet...
Or settle with the SONY PRS900. That's what I am doing - it's not perfect, I wish it had a bigger screen, but it gets the job done.
But an iPad... reading on anything retro-illuminated seems to bother some people more than others - but it sure bothers me a whole lot. And battery life. And weight. And Apple-wants-to-control-you....
