The Wi-Fi-only iPad 2 version is the cheapest of them all, and also the lightest at 1.33 pounds (601 grams). It improves on its predecessor in both desing and hardware, since the iconic tablet is now thinner than even the iPhone 4 at 0.34" (8.8mm). It is powered by a 1 GHz dual-core Apple A5 chipset, which provides 6x the CPU and 9x the GPU performance of its predecessor. All the while it keeps the same 10 hours of battery life. Dressed entirely in black or white this time, the iPad 2 sports HDMI output via a separate cable, as well as rear and front-facing cameras.
