Explorers have five hues to choose from when picking out Glass: Charcoal, tangerine, slate, cotton, and sky. (These shades are also known by the names black, orange, gray, white, and baby blue).
Glass buyers are asked to choose which palette they'd like during the pre-appointment phone call, but I was asked again in case I'd like to change my decision last minute.
I still went with what I think is the cleaner, more modern (yet futuristic) look: "Cotton."
There are a few steps to take care of ahead of in between the scheduling call and the Glass fitting itself.
For starters, explorers are asked to set up Google+ accounts -- if they haven't already. (It might be shocking if someone in this program didn't already have one considering the test pool is made up of Google fanboys -- or at least tech nerds who are likely social media savvy and must have set up a Google+ account, even if it's not active anymore.)
The Google+ account is considered vital to the Glass experience because users can share photos and videos recorded on Glass with their Circles and "the world."
There isn't much else to do with Glass beyond sharing photos and videos yet, so users might as well comply.
Explorers are also asked to enable Bluetooth tethering on their mobile data plans for pairing the device with smartphones.
(More on this later as there is a loophole of sorts for Android users, but not so for iPhone owners).
