Get apps on the iPad. When you’ve got a WiFi or 3G connection, tap the blue App Store icon on the Home screen and browse away. At the top of the Featured screen, you can see what’s new and hot. At the bottom of the screen, you can tap to see what the iTunes Genius thinks you might like, see a list of the most downloaded apps (Top Charts), and check out apps listed by category. When you find an app you want, tap the Free App or price button; the latter turns into a Buy Now button (circled), so hit that. Type in your Store name and password (even if it’s a free application), and the download begins. After the program finishes loading and installing, tap its icon to launch it. Download times vary by app size. For example, the beautiful interactive textbook pictured here, The Elements: A Visual Exploration, is a honking 1.71 gigabytes—so give it time.
