For $499, you get you 16 GB of storage, with WiFi built-in. For $599, you get 32 GB of storage. For $699, you get 64 GB of storage.

The 3G models cost an extra $130 each.

So all told, there are six models of the new iPad. The most eexpensive 64 GB model, with 3G, costs $829 plus the monthly charge.

The iPad is powered by Apple’s own custom silicon, he says — a 1 GHz A4 chip,, 16 GB of memory, 32 or 64 Gigabytes of storage.

There’s Wi-Fi, 802.11n, and the latest Bluetooth. (Apparently no 3G wireless, notes my colleague John Markoff.) Accelerometer, compass, speaker, microphone.
