I read a lot of ebooks on my smart phone, and they all come from Project Gutenberg. In other words, they’re all free. When I recently migrated from my venerable Palm Treo 700 to a new phone, a good ebook reader was a high priority.
In fact, finding a good ebook reader was deal breaker – I wouldn’t keep a phone that didn’t have a good reader. I settled on a new Blackberry Storm 2 and Amazon’s Kindle for the Blackberry. While not perfect, the Kindle software serves its purpose well. And I still haven’t had to pay for a book.
