eReaders are getting powerful enough to become fully-fledged Internet tablets, but gaming devices? That's a new spin. Turns out Qualcomm has a detachable game controller add-on for that Snapdragon-powered eReader prototype we first showed you on Wednesday. Take a look:

Qualcomm says it'll be up to the various manufacturers to create devices built on this reference design, but Wi-Fi and 3G connectivity would make multiplayer gaming pretty interesting. Just depends if ARM-based operating systems, like Android, get the right games.

The concept has a 5.7-inch display that uses Qualcomm's "mirasol" screen technology that provides better battery life and smooth video playback. Problem is, for now, this reference is just a static-image prototype. Yet another eReader angle that we'll be watching for you, though. [SlashGear]
