These are two entirely different things. Is the goal to get them to troubleshoot a computer, or are they being issued laptops to enable their education? If it's the former, then I can kind of understand. Trial by fire and all that good stuff. However you just said yourself:

> we teach them basic math

Keyword here is teach. We do not give them a math book and tell them to figure out what 8 * 7 means. We break down the concept of multiplication into its constituent parts. In that same vein, we should enable the child to learn how to troubleshoot the system.

Like I said: I think we can put Timmy's time to better use.
