The photo app is fine for viewing images, but it falls short elsewhere. You can't view videos that are mixed into a photo folder, for example. And though you can view an image, e-mail it, turn it into wallpaper, or copy it, you can't move it to another folder or can you view the file name.

The e-mail app has also been cleverly redesigned to take advantage of the spacious screen. For example, in landscape mode, the e-mail app shows recent messages and a search bar at the left. The selected message appears on the right--an approach that isn't viable on the iPhone's smaller screen.

The Calendar app benefits greatly from the iPad's display. Calendar entries are more readable, and the day and weekly views look terrific, with more detail visible onscreen, and easier navigation to other days in a month. You can easily switch among different calendars for your household, or view a list of your events for a given month. Regrettably, however, you can't print it natively, nor can you e-mail entries to yourself or to others.

The highly visual iPod library looks very different on the iPad. You can easily see your library options (music, podcasts, audiobooks, purchased, and playlists) in a pane at left, and then see the content of each in a pane at right. The playback varies slightly from the iPod app on the iPhone: Here, the playback buttons are in the upper right corner, rather than at the bottom of the device.

The ability to edit playlists on the fly is a welcome addition, and it's extremely easy thanks to the extra screen real estate. You can play music in the background as you move around the devices, too; playback will end only if you activate a second app that requires audio.
