Apple just made the beta version of its upcoming operating system update available for download. Engadget Managing Editor Dana Wollman took a look at what we can expect in her Yosemite preview.

Is Kindle Unlimited worth the cost?

Amazon's new Kindle Unlimited service gives you all-you-can-read access for $10 per month, competing against services like Oyster and Scribd. Engadget's product database manager, Kris, wonders whether the service is worth it. She argues that it's easy to binge-watch shows and movies on services like Netflix, but it's much harder to binge-read a series of novels. Will you be subscribing to Amazon's new service?

Silly model numbers from Microsoft and Nokia

It should be pretty easy to figure out which devices are better based on model numbers alone, right? A "2" is bigger than a "1," so "2" must be better. Take the Nokia Lumia 520 and Lumia 530 for example. TgD examines the differences between each device and wonders whether the Lumia 530 is really better than the Lumia 520. How do you feel when manufacturers do this?

Where are all the MMO mice?

Massively multiplayer online games are some of the most popular types of titles that people play. There was a time when hardware manufacturers like Razer and Logitech made gaming mice that specifically catered to this group. However, Quaddragon feels there's been little innovation in this area. Where are all the good MMO gaming mice?
