If productivity and possible note taking etc are factored in I don’t think those Amazon tablets, (well the HD8 because that’s what I’ve used) would even be a Vauxhall Zafira in that comparison, more like a Honda C90, economical but you couldn’t get a chest of draws in one.
Mrs has the HD8 they are not “great”, although tbf Amazon were great when I returned it when the charging port died.
But y’know, whatever, I’m not fussed what Ms thepodge gets for university just think that bang for buck at £319 the IPad 2018 is an absolute steal (as is £50 for the Fire) and will, gods of consumer electronics willing, still be a useful device in 5 years time. The HD8 will most likely be landfill/responsibly recycled.
