I've had a Vita since launch, so if you don't mind, I'll give you my point of view on that list.
1. PSP games must be repurchased digitally and are very often significantly overpriced.
2. Everything on earth uses Netflix, and I've never been compelled to use it on my Vita.
3. Screen is great, but the ergonomical feel varies from person to person. I don't like the L and R buttons.
4. I highly disagree. There aren't many exclusives, and the good games that are there are usually available on console.
5. It's definitely not like a PS3 in your hand. Compare Mortal Kombat Vita to its PS3 brother. It's more on par with an iPad 2.
6. This only works with very, very few products.
All that being said, I still really like my Vita and I'm very glad I bought it. But this dude's overselling it, a lot. I'm just offering a different perspective since there are quite a few super-pro-Vita-weenies out there.
Or maybe they aren't weenies, they just have a different perspective. Like:
1. If you never owned the PSP game in the first place you aren't repurchasing it. Also there are sales on PSP games every week. Every Atlus RPG is below $10 currently, for instance. Capcom just had a sale last week.
2. As far as picture quality and size there is no screen that is in the same ballpark for netflix as the vita OLED.
3. You did admit that it varies here. So no need to argue
4. There are a ton of exclusives. People seem to think that things are ports that aren't really ports. Wipeout, Uncharted, Modnation, Dynasty Warriors Next, Unit 13, Hot Shots, Army Corps of Hell, Mutant Blobs Attack, Lumines, Super Stardust Delta, Sumioni. Gravity Rush and Escape Plan are all Good to Great games that aren't ports (some are series that exist on other systems, but they are new entries).
And the ports that are there... are amazing. Mortal Kombat is crazy good and has a full vita specific challenge tower, Marvel vs Capcom and Blaz Blue are also great... making the Vita one of the best handhelds for fighters in just 4 months. Disgaea 3 is fantastic. Rayman Origins is perfect on the device. FIFA and Virtua Tennis, and MLB The Show are all incredible and paint a very bright future for sports games on the device.
I just don't understand complaints about the vita library. I mean if you want to take a dump on the gameloft ports that ubi brought over, or Reality Fighters or the AR games, fine. But the rest of the lineup is goddamn amazing.
5. It's not a PS3 in your hands, but it's certainly more powerful than an iPad 2 (or 3, for that matter, which I own). You are fighting hyperbole with hyperbole.
6. "Very, very, very few products" = Buy Hustle Kings and get both. Cross play with Pure Chess. Cross game saves with MLB The Show, MGS HD. Retro City Rampage (if microsoft ever stops cockblocking it) will be buy one get both. Motorstorm RC shares online data. Ultimate Marvel vs Capcom has buy once get both for DLC, Modnation allows you to play user created tracks from the PS3 version, and Stardrone Extreme has cloud saves to swap back and forth.
It's not a giant list, but for four months it's far more than "very, very, very few products."
