- the thoughts/attention, effort and time spent to
- use it
- decide where to store it
- worry about losing it
- find it if it's lost
- decide whether or not to keep it and then how to transport or dispose of it during a move
- the space it takes to store it
- the time and effort it takes to maintain it
- the loss of neatness to clutter...
It's not really free, is it?
