came up with a very short-term solution for the cold metal back until I figure out if I'm keeping this thing. removable glue dots and a piece of craft foam I have that, interestingly, is the exact size of the back of the Oasis with no trimming. kind of kizmet-ish.
the glue dots will come off with minimal residue that can be easily cleaned and I can reuse the foam should I need to. short-term because the foam is a little stiff and thick for real use.
I use these for a lot of things around the house and have some left.
