See for me back when the PSP launched it was probably the ebst portable tech for me and my buds at the time, it had most of the games we hoped for and wanted. Fast foward to now and the Vita has less of what I wanted from the original PSP while asking me for more money and putting up with the new memory card system that screwed over my options, I just didn't see the point in even buying one, one of my mates who bought the original PSP bought the Vita and then realsied over time the dust it had collected and the interest with it dying, we both ended up going for a 3DS by the time Pokemon X & Y launched, I got a few games like Animal Crossing and I've been playing my 3DS since.
I'd say Sony just made the device too expensive, it had less first party titles than the last model, their previous model before the Vita was an all digital one and we all know how that one was recieved, that and their memory card system really threw people off, not everyone but enough for some to not bother buying the thing.
They also released it too early, launching it during 2013 if not 2014 would have done the device better because while it was failing they decided to then pair it up with the PS4 to make it look appealing by using the popularity and power of the 4 instead of using the power of the device itself and focussing on it rather than having to pair it to make it stand out.
Mankind, in its arrogance and self-delusion, must believe they are the mirrors to God in both their image and their power. If something shatters that mirror, then it must be totally destroyed.
