Developer: Sony Computer Entertainment
The PlayStation Vita was Sony's second handheld console, and the successor to the immensely-successful PlayStation Portable.
While it enjoyed success in Japan, it was overall a commercial failure, with one contributing factor being the high price of its proprietary detachable storage (for instance, a 32GB Memory Card cost $120, half the price of the system itself).

Hidden Copy/Paste Feature
Add a link to the plugin.
There is an copy and paste feature hidden in the system software. The feature was actually present in very early versions of the PS Vita firmware but starting somewhere around firmware version 1.06, it was disabled for an unknown reason, though it can be re-enabled using a plugin.
