Playing PS1 classics on Vita has given it a new lease of life for me recently.
As someone who doesn't mind replaying old games, between PS1 classics/PSP games and the stream of Vita titles, it's an excellent device.
But if you were just waiting to play new Vita titles... well, it might be a bit of a rough ride for you. Which is a shame.
I hope the console finds its feet. It does deserve it as a piece of hardware but sadly Sony themselves seem to think otherwise given their efforts towards it.
