Hi All, Alex and Marcello are both wrong! Though each in some aspects are correct! First, resolution SHOULD generally, produce better results! But, since one threw the image quality of cameras! I laugh at all those nice little cameras that have 10, 12 Megapixel senors. They should be able to make better than my SLR (8 mega, 8 years old) Well, guess what! they do not! So, resolution is not everything. For cameras there are other factors which effect image quality! My friends are always asking me to take pictures for them to because my are better, even though they are taking pictures themselves. They, also wonder why I do not have a smaller camera!! ;-) So much for the user experience and preferences. The same resolution problem is true for ebook devices! Higher resolution gives you the ability to display finer detail. So, the characters should be more defined and offer a better reading experience, and should cause less eye strain. Eye strain was mentioned (at least indirectly). What do the doctors say! You guys can not be serious that reading on "Phones" is healthy for you! Convient, yes! So, even though higher resolution is more pleasing, it will depend on the quality of the displayed book and program used to display it! (In case anyone is wondering. I do not own a Kindle, iPhone, iPad though I have studied them in stores) Touch screens are the better input devices, if designed properly. It is also, the direction of the future computer are going in that direction, it is even truer of tablets and "Phones". On the other side of the user experience. Nostalgia! Remember, the discussion that the printed book will never die! The experience of flipping those pages!! The cold touch of these reading devices! Depending on device you have the sound of that turned page! Size! Larger screens are better. I would think, 9" to 10" would be best for a portable device! What I am missing is the "epaper" displays. They seemed to have disappeared. (epaper where these foil thin displays, lightweight and flexible, had decent resolution, too) In my opinion all readers are to bulky and heavy. I do have to agree with Marcello that the iPad, slightly on the heavy side. But, that is not because of it weight but size. Yet, I see no way of doing it better and as a avid laptop user, find it quite acceptable. A Book is a lot bulkier if not heavier. Price! Dedicated readers are far to expensive, The DX cost as much as an iPad. Yet, from which device do you get more for your buck $$ From what I seen what can be done with iBooks you would think the user experience, would expect that more would get on the band wagon. An iBook has more look and feel towards a printed book. And more, for the user experience. For example, books for young kids (remember pop up and the like). Full color spreads!. Hope IBook comes to the Mac soon!! O.K. O.K. O.K those things PG et. al. are not interested in. But, we are talking about formats, and abilities of devices and standards! regards Keith.
