We now know when the first iPads will be available for sale in U.S. Apple Stores: April 3rd. We now know what kinds of iPads you’ll be able to buy at that time: the WiFi models only. And we now know when you’ll be able to pre-order your iPad via online delivery or Apple Store pickup: March 12. All of this information came out in a company press release Friday, along with the obligatory Steve Jobs quote saying something about consumers being able to “connect with the apps and content in a more intimate, intuitive and fun way than ever before.”
