That's not a good rebuttal. The context is $250 laptops that afford students technology literacy for cheap. Not, I can't afford a yacht and I'm ok with it, ergo everyone else can be ok with things they can't afford.
My netbook from 2009 that is still working, was sold with a Linux distribution, and gotten multiple Ubuntu updates, and is still working perfectly fine.
Its price? 300 euros.
So apparently not something that is only for people that can only afford yachtes.
Well, there is some blame to be put on education system for not going open, but chromebooks are significantly less IT maintenance than average linux laptop.
In ideal world it would be non-profit partnering with hardware vendors to produce <educational linux distro> and certify various devices for it. Then non-profit could continue to develop the systems and vendors would have incentive (schools will buy your hardware) to help.
