TVs are getting trimmer. LG showing off a 55″ Organic LED that’s just four millimeters thick.

Smartphones are growing. Sony’s Xperia Ion is an Android device with a massive screen and PlayStation game support. It’s designed for AT&T’s 4G LTE network.

Tablets are getting cheaper. Asus hopes its Transformer Prime — at $250 — deserves consideration over the iPad and Kindle Fire.

Nintendo showing off its Wii U console: it replaces the stick-like controller with a touch-screen tablet — though the gaming company says the cheaper wands will still work with the new device.
