It would be nice if Amazon released a version of the Kindle software to be used on an actual computer.

Is there some sort of hidden assumption that people will never read an entire book on their computer, only on a portable device? Maybe I am just biased against the idea that no one reads a book on their computer since I do it all the time with technical books that can be purchased in pdf format.

A Kindle software app would open up (as in make available, not DRM free) a lot of books from publishers that do not have any sort of digital download of their books.
