Maybe if...
I can walk into my favorite library, select 3-6 titles, electronically, and have them delivered to a SD at checkout, a SD that I could easily slide into my ebook reader.
I am engineer with more than 300 books and essays collections about engineering, between 120 and 140 novels and short stories and another 200 books about physics, education, mechanics of fluids, probability, numerical methods, and so on. So, they occupy 6 large bokshelfs around the apartment (including 2 on my child bedrrom)., so yeah, I really see the need for an efficient ebook readfer, with costing no more than 200 bucks.
