not we all know that Li-ion 18650 are not there yet, not even close.
This is going to be an exciting project. I'm not sure which one I would prefer yet, but I might be leaning toward larger case with all of its extra attachments.
I am currently using the Boxwave AluArmor case, but I'm pretty tired of flipping it open in order to get to the keyboard. The one thing I would really miss is the belt clip this case comes with. Would it be possible to put a screw hole on your new case to use a swivel belt clip? http://www.boxwave.com/swivel-belt-c...el-d/bwpd/fmz/
