user36281: Is it possible 2 maintain a single HD wallet on two devices? Assume a laptop and phone. My first thought is to install a HD wallet on the second device and create a new wallet using the original wallet words.

user35923: Yes with an HD wallet you can use as many devices as you like.
However you may want to ask yourself why you are doing this. More devices = more possible attack surfaces.
Using different HD wallets has the benefit of the losing one (to a keylogger, etc) not causing loss to your Bitcoin in the others.
Why not keep a small amount of BTC in your mobile HD wallet for everyday use and have a little more in a seperate laptop HD wallet and the majority in a seperate cold storage HD wallet?
