Well I am considering the dive. It seems more and more often releases I am interested in offer only hardcover+kindle for quite some time and only begrudgingly offer paperback. Given I dislike hardcover books I am unwilling to pay the premium they demand over other formats.
However, the problems with reading books on a screen is eye strain. Even as I type this my eyes burn and burn and burn. And I haven't even been looking at the screen that long. Meanwhile I can read printed books for 10+ hours only taking breaks for bathroom and maybe to get a snack. Even with my cellphone I can not read it without my glasses(as in the screen is just a blur even at book distance). In contrast I normally read printed books without my glasses.
I am just not convinced that such devices are worth the price tag(particularly not now since I just had to get a new car). To top it off apparently they can't agree on a common format. I absolutely loath dealing with cross platform crap. At least a printed book is a printed book, it doesn't much matter where I got it from.
So talk about the different eReaders so I can try and come to a decisive decision. Currently my leanings would be towards the Kindle if only because I am a Prime member.
