For the love of God... no, just no...
I have a PS Vita and I love it. But doing this would be a complete waste of money. Also, there are various things I love more about my Steam account than my PlayStation Network account, for instance, Steam sales and the ability to download and play my games on any of my computers. The PlayStation Network limits you to around 3 systems I believe. There's also the fact I love my PCs more than my Vita. I'm that piece of the market that prefers gaming on the PC(whether it's a mobile pc or a desktop) but buys consoles largely for exclusive Japanese titles(actually, technically, I prefer the Linux platform and universal, interchangeable hardware to everything, but most games use DirectX over OpenGL and are Windows and not Linux compatible, also most laptops are difficult to change parts other than RAM memory, but the general principle of freedom in the "personal computer" and the universiality of the platform is why I prefer it to all other platforms).
Don't get me wrong, I love consoles. I grew up on the SNES and NES in a time when home computers offered lots of possibility for businesses, but not much in the realm of home entertainment. But while the SNES competed a lot more strongly with the home computer than and what DOS/early windows/Mac had to offer, home computers have a lot more of that content than ever before. And about all the consoles have to offer, unlike the glory days of the SNES in the 16-Bit era, are exclusive video game titles, most of which are made in Japan. My computer has become my SNES for many years now. Not just because of emulation, but because of a greater PC library and the fact that my PC is my main hub for the great deal of internet browsing and posting, 1080p video watching, and the other things in the great deal of variety the PC does. Realizing this, console companies, now, too, are including browsers and video playback tools. The PS Vita is no exception, but the formats of video playback are very limited and the browsers tend to not be very good, and the Operating Systems of these consoles and handhelds just can't compete with Windows or Linux. Nor do they have the wonderful ability to each new good piece of hardware that comes along like an HD 7870 or 3570K CPU. And that is what makes the PC, my new SNES.
And please, let me have a Japanese PC exclusive for once. I don't want to lose those, too.
