Wow. I just have to say I was just introduced to the Palette product for editing and I have to say I am dying to try this myself. I use a Wacom tablet currently but I love this concept. The buttons and scrolls for selecting images and the sliders for the adjustments. I really find this to be exactly what I want to edit.
I can't wait to try this myself and then if all is good order.
Go to Palette on Facebook or Palettegear.com to check it out!
