I love the convenience of eReaders but still find them overpriced. I'm eying Amazon's new Kindle with wireless charging. Hopefully Black Friday will bring some decent price drops.
Multiple stores here in Australia are already doing or will be doing shortly the new paper white for $169 instead of $239. Including Amazon directly. I’d check deal sites that cover your location, you might not have to wait.
Compared to equivalent book storage (and costs), the device price becomes far more reasonable.
Smaller devices (6--8") are at or below $200, particularly if you're willing to go back a model rev or two. Large devices are more expensive (~$800 for a 13.3" screen), but permit 2-up reading of much content and full-size (e.g., unzoomed) viewing of even large-format or small-print materials.
