PS Vita, the most powerful handheld video game console ever, is out now. Have launch day nerves? Here’s what you need to know. Sony is selling two different SKUs: the $249 PS Vita with WiFi and the $299 model that also packs in 3G from AT&T. (Also available are the $299 Launch Bundle and the $349 First Edition Bundle, but these are being sold in limited quantities.) If you opt for the 3G model, AT&T is offering up tiered data plans that go like this:  250MB ($14.99), 3GB ($30), and 5GB ($50). There are 25 PS Vita-specific titles from first and third party developers, and the standout must-buy game is Naughty Dog’s Uncharted: Golden Abyss. In addition to fantastic graphics, Uncharted takes advantage of many of the Vita’s innovative input functions including the dual analog sticks, the six-axis motion sensor, and the touch-sensitive back; and so the game will help acclimate you to the new handheld. What else? The PlayStation Store has been updated with Vita-specific apps including Facebook, Netflix, LiveTweet, and Flickr; these freebies are necessities for early adopters, no doubt.
