Possibly the worst "nailed it" candidate I've ever seen.
For a start, there were PLENTY of Vita deals around that either reduced the cost or added in games, memory cards, Plus subscriptions and other extra value items to improve the deal. "Pricey" is a ridiculous comment when looking at the amount of tech involved in the Vita - I assume, given the overwhelming level of praise in the part of your post I haven't bothered quoting, that you don't consider $300-$350 for a Wii U "pricey" given that from specs it barely appears more well-equipped than that console you refer to that came out six years ago.
It has been far from "callously abandoned", that comment basically made your entire sarcastic putdown of the poster you quoted irrelevant, as you clearly haven't bothered to keep up with Vita developments if you think that's the case - you'd prefer to just jump on the Vita doomed bandwagon instead.
Given that plenty of Sony franchises have already got titles on the platform, and titles are still being released, plus those upcoming, and the addition of PS+ to Vita, it presents a very different picture from the one you do.
While the original post was flawed (as remote play is abysmal currently on the Vita), your response was even more so, as you didn't appear to give any reasoned argument, not to mention the situation not being anything like what you mentioned.
