If you use the iPad camera connection kit you can import your pictures onto your iPad. This presents a problem when you get home to find that you have pictures on your iPad and on the memory stick. You would not want to import your pictures twice. There’s no way on the iPad to delete pictures except to select them one at a time. This can take a very long time. You could import them into iPhoto and use the delete function but that would result in duplicates in your library.The simple solution is to use Image Capture. Select all of your pictures and choose delete.
