There's no reason the MNT Reform cannot be used both on the go and in a docking station. The parent likes to use an "old fashioned" (I disagree with that judgement, but fine) paradigm of portability, so what? Does that make it a less valid choice? "Portable" is a generic term that's not reserved for discussions of any specific kind of portability, so why not coin/use a specific term for "fits in your pocket and is usable on the train" if you need one, rather than silently assume?
