The wi-fi+3G models will cost $629 for 16GB models, $729 with 32GB and $829 for 64GB – suggesting that doubling the memory costs $100 a throw.
Apple claims that these models will deliver 10 hours of battery life if using wi-fi, and nine hours of surfing the web using a 3G data network.
AT&T will provide the basic infrastructure for 3G with pre-paid data plans for the iPad.
Apple said it will announce international pricing and begin taking online pre-orders for iPad on May the 10th. As Apple says in a footnote, “actual results vary”.
