Saying I have no idea what I am talking about doesn't make it true nor does it make you correct. I know exactly what I am talking about and if the school can't afford to upgrade their hard drive they have several options, one they can delay their lifecycle, two not allow personal stuff on work machines, or three gonwith a competitors laptop. If you deny those are valid options then you have no idea what you're talking about.
You don't have a very good understanding of how IT works in a school based environment - your posts have demonstrated this. Of course schools have those options, but it does not take away from the fact that the non retina pro was a great machine for schools for many many reasons.
Please define "loose" a lot of education market share. Maybe start by looking up the definition of loose.
Oh wow, I made a typo. Please define "gonwith" - maybe look at your own posts before attacking mine.
