Asda are selling the old OLED 3G / Wifi PlayStation Vita for £120 right now. Click here to buy >>
If you're one of those people who absolutely must have the very best quality gaming out there, then definitely try to snap up an OLED Vita while you still can. Suree, the battery is marginally more rubbish than that of the Slim, but that screen. Mmmmmm... that OLED screen.
You probably won't be able to tell the difference between this and a Slim unless you pout them next to one another, but you'll know deep-down that yours is the graphically superior model. And that's a nice warm feeling to have. Technological superiority is awesome.
Do be aware that the packaging might be a bit damaged on this item, mind, though the console itself is in "original manufacturer's condition".
