Texting and Web browsing just got easier
The Wireless Keypad, as they're calling it on the official PlayStation.Blog, is a shiny new toy for gamers who have too many friends and like to browse the internet with their PlayStation 3.

According to the blog, the Wireless Keypad will have many features, including a mode that turns the main key area into a touch pad. Like a laptop computer, you simply slide your finger over it to control the cursor, tapping to enter (or "click" as with a mouse), and two shortcut buttons on the Keypad will "enable users to jump directly to the XMB’s 'Friends' icon and the 'Message Box' during gameplay."

The PlayStation 3 Wireless Keypad also acts as a Bluetooth device, meaning it can connect to any Bluetooth enabled device with Keyboard functionality, such as a smart phone. To charge the Wireless Keypad, users just plug it into the console's with a USB cable.
It is currently scheduled to launch in late November.
