Today Apple announced that the long-awaited iPad will be available for pre-order on March 12 and the Wi-Fi model will be available in stores on April 3. The Wi-Fi plus 3G model will be available in late April, the company said. The Wi-Fi model can be reserved on Apple’s website and available for in-store pickup on April, 3 they said, but let’s face it – it will be virtually impossible for store’s to have enough iPad’s in stock to sell both the pre-ordered Wi-Fi devices and to shoppers who line up to be the first to have the new device. One interesting note in the press release: “Battery life depends on device settings, usage and other factors. Actual results vary.” Right . . .
