The more powerful applications available, the more powerful the device is. That is no surprised anymore since a larger number of third-party applications are starting to make theirs presence on handset devices. Photoshop CS 5 for iPad is no exception in this trend.
Adobe has finally released a specific Phot0shop CS5 application for iPad. The price is very reasonable in comparison with desktop version. However, you should keep in mind that, the new release is only a limited version, meaning you can not do lots works with as regular Photoshop CS5.
