Based on the latest patent application from Apple (20110119609), it seems that Aperture might be coming to the iPad:
Methods, systems, and apparatus for managing elements in a user interface for a software application executing on a computer system include displaying a user interface having separate elements including at least an image browser element for viewing preview thumbnails of available images, an image viewer element for accessing a selected image and a Heads-Up Display (HUD) element that displays metadata for the selected image; receiving user input requesting that the HUD element be moved from a current location in the user interface to a destination location in the user interface; and modifying the displayed user interface by moving the HUD element to the destination location and selectively altering a size or location or both of one or both of the image browser element and the image viewer element to accommodate display of the HUD element at the destination location in the user interface.
Adobe is also working on releasing Photoshop and Lightroom versions for the iPad.
