Before you respond with "My wife has 15 purses & they all do the same thing!" indulge me for a moment.
I'm a professional photographer & I travel to South Africa & Tokyo often on shoot assignments on location. I also do the corporate thing by day & the Coffee house art circuit in between.
My case adjustments occur on practical reasons for the situation/condition.
The answer to how many cases does it take to live my life?... (3)
1. Hard Candy Street Gear (Hard Rubberized/ protective faceplate & backing for on location shooting in the field)
2. Black Gel Case (Basic coffee house/lifestyle chillin')
3. The Apple fold-able/stand-able black svelte case (for the office/meetings & data capture)
So what's your number? Let the games begin...
