Storing my data at my house makes sense, especially if upkeep of the box is relegated to the end user. Storing my data at the tower in my neighborhood, instead of a regional center seems to be a large increase in maintenance cost for a minimal decrease in latency.

Accessing the tower is expensive in time, and equipment that runs at the tower is exposed to a wider variety of temperatures and RF stress than in a nice warehouse somewhere in the metro area.

It's possible the right caching at towers could reduce the backhaul bandwidth requirements, but seems iffy.
