Is there a reason you are against the Kindle? I am, but for my own reasons as listed below. The reason I ask is they have released the Kindle SDK and if it is the hardware you are against (like I am) then I might suggest using the Kindle Reader app on an iPod Touch, for example. Okay, actually that is probably a bit small, but it is a feature you can look for on non-kindle hardware if you are interested in being able to take advantage of a lot of the Kindle offerings...
I am somewhat against the idea of the Sony ebook readers, but I have seen them in action and they seem nice sized as well, if a bit slow. Expensive, and the battery life is unknown to me, but the size is about right for reading longer passages or books. My problem with them is Sony's love affair with DRM and rootkits, coupled with the high price and apparent preference for proprietary formats (not that Amazon is any better with the Kindle and in some ways is worse). Okay, guess I really didn't have much to add to the conversation. NEXT....
