I have been researching a few eBook readers in the hopes of finding something that will assist in my studies without adding more paper to my bookshelves. I still haven't made a final decision yet, but was (as of late) leaning toward the Kindle DX which has a price point of $489.
At least I was until today...
I'm thinking at $499, I'll get better file organization as compared to the Kindle DX, with the addition of office-style apps and web surfing, among others. We'll see.
