Apple iPad 3
OS: iOS 5.1.1
List: $499 to $849
Network: Wi-Fi, 3G, 4G
With the iPad 3, Apple beefed up the processor and packed in more communications and screen pixels while keeping the starting price at $499. The Retina display offers 2,048-by-1,536 pixel resolution, double that of its predecessor. Driving all those pixels are four new graphics cores in the ARM Cortex-based A5X system-on-chip. And its iSight camera captures 1080p video at 30 fps with audio and image stabilization, a big step up from iPad 2's 720p capability.
Thanks to iOS 5.1.1, iPad 3 can now be configured as a Wi-Fi hotspot for as many as five devices. There's also Bluetooth 4.0, which is backward-compatible and adds high speed and low-energy protocols. Wi-Fi capabilities are identical between old and new models. Pricing starts at $499 for Wi-Fi-only models, and $629 for 4G.
