iPad in the Dark

Then I discovered a feature of the Kindle app that the Apple iBook app lacks: reversed fonts – white type on black pages. This is a silly idea for paper books: hard to read and a colossal waste of ink. It is also a silly idea for ordinary Kindles that, like paper books, are read by reflected light. But with a self-lit, back-lit device like an iPad, it becomes a new way to experience books. Even with very low light levels, the contrast of the white letters against the black page is outstanding. In a dark room, it is very readable.

Funny how with all the advanced technology, all it takes is one tiny feature to change the experience: there is practically no excess light to bother other people.
