I'm considering getting Photoshop touch for my iPad... But as I'm a Graphic Design student I'd like to know how easy, if possible, is it to open the PSD files on my Mac CS6
Yes, you can open Photoshop Touch files in Photoshop desktop with the psdx plugin:
However until now layers in psd files will be flattened on importing in Photoshop Touch.
Thank you very much... You say "until now", are you saying the files still flatten upon opening or the latest version remembers the layers?
No, they are still flattened. You would need to import all layers as separate files (via Creative Cloud).
