It never should have been put in. Really don't know what Sony was thinking with the Vita. At least support it yourself.
They were thinking 'how do we make a new version of the PSP?'. Problem is, the market had changed so much that a new version of the PSP was only attractive to a tiny weeny minority of people.
They do support the device as much as can be expected (given they just launched their flagship console). The problem is that isn't enough to offset the lack of solid third party support.
