It's been less than two years since the iPad first landed, but Apple is ready to make the only tablet worth buying even better. Headlining the list of new features on the iPad 3 ($500-$830) is the drool-worthy Retina display, which densely packs in enough pixels that the human eye is unable to distinguish individual pixels when held at a reading distance — you know, like that iPhone 4 in your pocket. The new iPad and that crazy screen is powered by a high performance A5X chip with quad-core graphics (which is still is smart enough to deliver 10 hour battery life). There's also a slick 5 megapixel iSight camera with 1080p HD video recording capability. And for the first time, you can get built-in support for AT&T's and Verizon's 4G LTE networks. Apple also today introduced the iPhoto app, along with major updates to iMovie and GarageBand, completing its suite of iLife apps for iOS. Like always, the latest iPad is available in black or white. It comes in 16GB, 32GB, and 64GB capacities. It will be available on March 16th.
