Here are my reasons why I would never get a Vita.
-Price. It's the same price as a brand new PS3. Is it better? Not to me. It has its advantages and disadvantages over the PS3. But I'm pretty sure that if given the choice, most newcomers would buy a PS3.
-Not backwards compatible. Sure, you can download some games. But what about my old games? What am I supposed to do with them? Am I suppose to sell them and get like 50 bucks for all of it? No, sir.
And I know this not-backwards-compatible thing isn't new. But companies usually give us time to get over that fact. Like the old 360s, like the clunky PS3s, like the original PS2 did, like the 3DS, like the first Wii models...
-Very few exclusive titles. See, the only reason I was gonna buy a 3DS was for Megaman Legends 3 (And we know how that turned out...). The only good, exclusive title I can think of is Uncharted: Golden Abyss. The others are adaptations of games already out: ModNation Racers, UMvC3, Final Fantasy X (Which I love, but still),Disgaea 3...Sure the 3DS had a horrible launch-up selection of games, but at least they were planning on releasing better titles: Kid Icarus, Super Mario 3D Land, Mario Kart, Resident Evil Revelaitons Revelations, Kingdom Hearts, Theatrhythm Final Fantasy, etc. I'm not saying those games are amazing and life changing, but at least they learned from their mistakes: They lowered their 3DS price, they gave away free games, etc. Which brings me to...
-They're too proud to learn from their mistakes. Look at the PS3; it's the most expensive console out there (360: $200, Wii: $150). Sure, it's a blu-ray player and it has some exclusive titles (Hey, I'm a PS lover!), but when people are asked what console to get, they usually go for the 360, simply because of the price tag. I see it at work everyday.
It's still too early to say if the Vita sucks or not. We'll see. But for now, I say it's not doing as bad as the 3DS when it was released, but its future doesn't look as bright as the 3DS's. So far.
