German company txtr seems to be coming out with the world's cheapest eBook reader. At only $13 the first thing that comes to mind is "what's wrong with it?", and there's a few major caveats. The first is that there's no internal battery and it runs on AAA's, the second is that there's no dedicated data port, instead it relies on an android app to send books to it through bluetooth.
However it does appear to be functional, so those of you looking for something to read those humble ebooks on, you might consider this.
[...]world's thinnest and lightest e-reader device, weighing a mere 0.282 lb (128 grams) and measuring a mere 0.197 in. (5 mm) thick. The 5-inch (diagonal) footprint packs a 800x600 eight-level grayscale E-INK display, similar to the displays in older Kindles.
