Well guess its subjective, but theres still the issue of comparative game libraries, price, and memory card pricing

I was only referring to functionality. Hopefully the things you listed can be fixed with time.

Why the hell would I buy a portable console to play only in my residence?

Am I taking it to the Bar? No
Am I taking it to work? No
Am I taking it on vacation? No
Am I taking it when I play sports? No

Portable consoles are good for kids and adults that have down/commute time (flights, trains, buses, whatever) but as I'm not in this group, this product is not remotely enticing.

I hate it when people say a product "deserves" better. Vita doesn't "deserve" anything. It was built as a high-end portable game device. This is a product that, it seems, not a lot of people are interested in, and it has nothing to do with poor marketing. A poor product concept = poor sales = what the product "deserves". There is no reason why core gamers should be supporting it, other than those that actually enjoy it. I'm a core gamer and I don't like handelds. I stopped using my PSP once I got a smartphone. If I were to buy a handheld it would be a 3DS because it's cheaper and has ALttP 2 coming. I don't want to play gimped COD or AC on a handheld. I don't care about other Vita features because I get them already on my Sony XPeria phone.

If Vita gets a slashed price and some cool new games then it may be a more valuable purchase proposition. As it stands most view it as an unecessary product not worth its cost. Portable gamers seem to like NSMB, Pokemon and Monster Hunter, and those are only available elsewhere on a cheaper competitor. Products are purchased not because they deserve it, but becase they are worth it.  Right now the market is saying Vita's not worth it.

The Vita has niche games. Niche games, by definition, appeal to a limited group of people. The Vita is not a hardcore gaming machine, it is a niche gaming machine. If there's a few games that appeal to someone, they will be likely to buy it.

As it stands, there are very few people who can say "The Vita has a lot of games that appeal to me." One or two games just don't cut it. The Vita will need a broad selection of quality titles in order to compete. Re-makes and spin-offs - the majority of Vita's physical library - will never be system sellers, as they are niche, only appealing to a small portion of their series' fan bases. Digital games aren't system sellers, either, as a very small percentage of console/handheld owners buy them regularly. It's the games in the stores that matter, and to be blunt, those suck.

Soul Sacrifice is better than any 3DS game I've played so far...and anyways PSP's GTA's, God of War's and Final Fantasy's annhilate NSMB, Pokemon and Monster Hunter in terms of quality while also selling very well.

And laptops are cheaper than a handheld? Not everyone already has a laptop or needs one. And a handheld is much more mobile.

The problem with your viewpoint - and hence, your opinion on this matter - is that your idea of quality is purely subjective.  Quality is, in most uses, a fundamentally subjective term.  Saying X game annhilates Y game in terms of quality is silly.  What you mean is you like those games better.  I do too...well, I've never played Pokemon or MH and I do really like NSMB, but I have GTA and FF on my PSP and really like them.  But the point is, all that matters is what you like and enjoy.  If you enjoy Pokemon and get lots of play out of it, then it is a quality game.  If we are objective about this, many, many more people enjoy NSMB, Pokemon and MH than portable GTA, GoW and FF, so those titles must have more value - or dare I say quality - to most people even if it's not you or I.  That's why it's silly to say Vita "deserves" better.  It doesn't, because it's a product that doesn't offer people what they want at a price they will pay.

20-30 year olds do. The only people I don't see having one are maybe lower income people (their profession doesn't need a laptop) or people who haven't gone to college. 

A handheld may be more mobile, but I just don't see a need for a mobile device dedicated to gaming outside of long distance travel, unless you use public transportation. Those <30 min's of free time you might have throughout the day can be satisfied with a smartphone. If you have >30 min of free time, you probably are traveling and have a laptop with you.

ps vita is so good, it competes with home console... and that was the problem... it features a lot of home console game and not much portable games...
