This is the third post in the series about E-book readers, which are an intermediate gadget medium in my opinion. Something better and more open lies in our reading and viewing future, for sure.

This post by a Columbia University educator lists out why he won't use E-book readers, yet:

1. Too many proprietary formats: Each E-book maker forces users to buy book from a single vendor.
2. Too much vendor control: What if a vendor decides to remove a software feature that you liked?
3. One cannot easily lend e-books.
