To go back to the original list of questions, #4, there is no citation management software available as far as I know.

Overall usability is pretty good. As the owner of several tablets as well as an iPad, a Kindle and two eDGe units, I can tell you that the eDGe is great for certain things, like reading and annotating books and pdf files. For me, the ability to mark up a pdf is what really makes it useful. Of course, if you bought a Windows Tablet PC, and install Adobe Acrobat Pro, you can do the same thing, but that will cost about $3500. The iPad is great for consuming media (if you accept the whole iTunes thing) but it isnt great for creating anything, and marking up a pdf can be done but only with software acrobatics.

I would also add that having used the eDGe now for almost 2 months, it is very easy to get used to reading a book on the eInk side and then having an LCD screen right there for web-surfing or checking email. The two screen arrangement is very cool, and I like it very much, although I admit that the interaction between the 2 sides is not yet ideal.

I would definitely buy it again. I find it much more useful (especially for "doing work") than my iPad.

Software is available, but we do need better access. There is actually quite a bit of software that we can download, but we dont have access to the Google Android store, unfortunately.

As for the future, I am hopeful that we will get Android 2.2 in a reasonable period of time. I am also anxiously awaiting Kindle for android so I can access all my Kindle books.

The eDGe is a little bit big and heavy, but acceptable. The size / weight makes curling up with it to read a book rather difficult (for me anyway). The iPad isnt much better. The Kindle is the only one that shines as something to curl up with, since it weighs just 10 oz.
