Now that I've really thought more about it,
My draw towards more devices that are more specialized is probably a result of the period of time when I had to go without a cell phone.
The fact that one device breaking caused me to lose access to every utility probably made me desire redundancy.
A smartphone just doesn't provide enough fault tolerance.
I feel need a device for each category of use,
so that if I lose one, I'm not entirely up shitscreek without a paddle.
