Ledger Blue: an enterprise grade security device

OK, smart kids make it, and a cool name. 

Too sophisticated for me, skip the LCD, give me the red/green. Make it thin, durable, flexible.  Something I could take to a poker game, with a few beers and it feels like the ace of spades.

I put my hardware wallet in the set of handheld pointer devices, the brains, the necessary displays are elsewhere in the sandbox. The sandbox leaves plenty pof spaces for me and my 'mouse' to 'cut and paste',in the icons, price beacons and autotraded pits.
