I would say that Johny nailed this in three sentences. The kickdown of a lap top from a guy in charge of getting rid of old laptops hardly seems like much incentive for me. I am typing this on a computer that was kicked down to me from a guy in charge of hardware for a company. I had to help him move and provide some beers while he put it together, which sounds more reasonable.
I am not a computer person but it also seem pretty simple to go mobile and use all public computers that have no login for something like that which you are describing.
