I would expect any kid enterprising enough to break a laptop in order to
get it upgraded -- to also be enterprising enough to "hack" the
replacement to bypass any software restrictions. Only when the
replacement (despite determined attack) cannot be made better than the
original would the risk of kids "breaking their laptop" be diminished.
