I'd be more interested in the production team in Shenzen finding a cellphone protective case manufacturer in Shenzen and securing a contract to create on spec production runs of a rubberized cover in various colors, but all of the same spec to save on upfront production costs. Slap the meetearl logo onto the cover and sell it as the official cover on the meetearl.com website.
I also vote for Realtree or DigiCam style camo case and/or cover. Second choice is coyote brown.
My main concern is now to protect the solar panel and display panel from the beating it will take in my long distance backpack.
