With the ongoing battle between Amazon’s Kindle and Apple’s iBooks, e-books have been in the spotlight plenty. But audiobooks are still the easiest way for many readers to get a quick fix on the go. They can be enjoyed hands-free almost anywhere, and--thanks to Audible and iTunes--they’re as easy to buy as their e-book counterparts. Unfortunately, with that convenience comes digital rights management (DRM) that restricts how you can listen to your books. Enter Simply Audiobooks, a would-be Audible-alike website offering downloadable audiobooks--at least some of which are free of meddlesome DRM. Despite that advantage, this upstart bookstore can’t begin to compare to its better, more established competition.
