If you're a voracious audiobook listener and want access to as many books as you could possibly listen to, the just-launched Audiobooks.com streaming service might be worth looking into. Once you pay the $24.95 monthly fee, you have unlimited access to a library of 11,000 titles, and can listen to as many as you want each month through your browser or mobile phone. While there aren't apps available yet, you can stream from Audiobooks.com as long as you're running iOS 4.0 or Android 2.3 (and higher, of course). There's no support yet for BlackBerry or Windows Phone, but it should be coming soon.
Compared to Audible, there's both pros and cons for Audiobooks.com. First off, Audible can be significantly cheaper, with plans starting at $7.49 per month for the first three months, and its catalog is nearly ten times bigger than Audiobooks.com's offering. However, Audible's plans only give you access to one or two books a month, while Audiobooks.com allows for unlimited streaming for just two dollars more than Audible's two book plan. Audible also requires you to download books to your device, while you can easily stream from Audiobooks.com. Given how long it can take to listen to an audiobook, unlimited streaming might not be necessary for most people, but at least it's now an option for those interested.
