If I had to choose a new feature for a PS Vita with firmware 3.74, I'd suggest:
" VitaShare" - A built-in, easy-to-use file sharing system ps vita 374 firmware new
VitaShare allows you to wirelessly share files between your PS Vita and other devices on the same network, including PCs, Macs, smartphones, and other PS Vita consoles. If I had to choose a new feature
The PS Vita!
