The schools in india can barely afford computer. and so are not throwing them away 1-2 years later.

The better question is what the used enterprise computer market is in India. Given that engineering salaries are no longer an order of magnitude less than the USA, I would assume that there would be a large secondary market of sub $200 laptops and SFF desktops. Is that not the case? Do businesses keep them till the wheels fall off? Do they get exported overseas? Can schools not compete on price with middle class consumers for used computers?

I think they are implying that situations where 50+ small dell quad-core i5s are being discarded is not common in India.

That's why I'm talking about 10yr old computers (or maybe even older)
