I love the portability! I could go for months on a road trip with no internet and still have something to read!
The only thing that my Kindle can't beat is the feel of real paper. Turns out there is actually a "manga reader" built by progress technologies that uses real paper in the design. It's super expensive from what I understand, but it looks like an actual book and has two screens in a book style view!
eReaders are getting crazy :3.
