Great upgrade! if I might humbly make a suggestion… protruding buttons basically make the device unable to survive even normal travel without damage… even with the aluminum case, those buttons with snag and become points of failure. Making the case so that the buttons are level or flush with the surface of the casing would drastically increase durability for those who travel frequently and need a dependable device that isn’t going to break easily. I would buy several the first day :-)
