These are the things I treasure. My iPad allows me to create the newspaper of my choosing. It's also a mobile photography studio. I can use apps like Adobe Lightroom Mobile and Photogene to edit my photos while sitting in a cafe after a long photo walk. My iPhone is my mobile office. As a consultant, apps like Freshbooks and Tempo allow me to conduct business from anywhere.
My Moleskine note book keeps me sane. While writing apps like Byword are useful I find putting mechanical pencil to the Moleskine helps me clarify my thoughts.
The iMac is where I set to do the bulk of my photo editing and blogging. Of course, I need music. Streaming trance music over my Harmon Kardon bluetooth headphones calms the jumble in my mind and helps me focus on the task at hand.
Treasures. All of them.
