I'm a first time user of Photoshop- on my Lenovo Thinkpad tablet. Is there any sort of written material on the Touch version - a Users Guide for example?
A walk through the build-in tutorial should be a good starting point for you.
In addition you can watch some Video tutorials ...http://tv.adobe.com/search/?q=Photoshop+Touch&sortby=relevancy
Guido gives good advice. Start with the tutorials and videos. If you have questions, this forum is the place to ask. We already have lots of good information here. For information you don't see here, there's a community of people that can help you
