Amazon has updated the Kindle app for the PC. The update includes a built-in dictionary, the ability to read in either a single column mode or a multi-column mode, and the ability to browse your library in a tile view or in a list view.
The update comes as Amazon has introduced a way to give Kindle books as gifts via e-mail. The Kindle books given as gifts can be read on the Kindle as well as on the various Kindle apps. In September, Amazon launched a Kindle app for the web, in which readers can read Kindle books directly through their web browsers.
Like the Kindle digital gift giving feature, Kobo announced a similar digital gift giving feature yesterday. The Kobo feature, which launches in December, lets readers schedule the day they would like the book to be delivered.
