Thanks for the replies.
About the screen size, I'm still not entirely clear about it. I have a Kindle DX and it has a 9,7" screen like the iPad, however, they look different in pictures. Is the iPad's shorter but wider?
If someone had the chance to experience both Kindle DX and the iPad, what it's like when viewing an A4 sized document? The iPad's extra width make it more readable? Or because it's also shorter, the a4 documents won't fill the screen, leaving two black bars, one each side?
Finally, how fast it the iPad turning pages, zooming in and out and panning pictures and PDF files?
Thank you
