I really feel this is unfair regarding the Vita.
I remember the discussions before the announcement of the price and people were expecting it to cost a lot more than it did due to the tech inside. The price of the memory cards were expensive but the hit they would have taken otherwise would have been massive.
We also have to remember that Sony had taken massive losses on the PS3 and hadn't had the success of the PS4 to help shoulder the burden of a low Vita price.
Ultimately I think the biggest hurdle Vita had wasn't the memory card prices but the name itself. I knew tonnes of people who had a PSP and they had never heard of the Vita. If it was called a PSP2 I'm willing to bet that would have helped out quite a bit.
This is dismissive fanboyism. The main characteristics of greedy Sony were an over reliance on proprietary media and cables and the lockdown of the software experience to make the device harder to use except in the specific way Sony wanted you too. The Vita has all of these characteristics.
The charging cable is proprietary.
The media is proprietary and grossly overpriced, even for the time.
Using purchased content from other regions involved wiping the card and setting up your console from scratch.
And you mention the hardware as if it was as spectacular as the PSP was at launch but in reality the graphic capabilities were about on par with a high end smartphone which, at the time, wasn't immensely more expensive than the Vita itself.
Don't get me wrong, the Vita has many qualities I appreciate, like the God-tier d-pad, and it's one of my favorite portable consoles of all time, but that doesn't mean we should dismiss the things that it got very, very wrong.
No matter which way you pin it, the Vita is emblematic of greedy Sony and the opposite of the lessons they should have taken, and learned, from the PlayStation 3's poor launch. If you think a different name would have been enough to solve all of its problems I don't think you're being sincere.
