Photoshop is one of the most powerful and deep pieces of software available, a tool that professionals use to manipulate images in thousands of ways. Which makes Adobe's unveiling of Photoshop Touch for tablets very interesting.
Photoshop represents one extreme in the software world — it's an expensive, very specialized piece of software that has piles upon piles of tools and features. Apps for phones and tablets, on the other hand, tend to be relatively simple and inexpensive, focusing on doing one or two things with ease.
Photoshop Touch will attempt to bridge that divide. While it won't act as a replacement for the real deal for power users, it will bring familiar tools such as layers to tablets. It seems likely that if you need to do some image editing and you've only got an iPad, Photoshop Touch will be able to do many things for you. And at $10, it's a tiny fraction of full Photoshop's price. Will you want to uninstall Photoshop from your laptop? No, but this seems like a great addition to tablet app stores.
