Ds1 is dyslexic and the school have recommended that he use a laptop for note taking and homework. His bag is already so heavy that I can barely lift it so I want something lightweight.
The lightest I have found is an 11" Sony Viao, but it's also the most expensive at 515Euro. The alternative seems to be a 13" Toshiba at around the same price.
My other consideration is lifespan, as most people have told me it will probably only last 2 years or so before it starts slowing down. He is only in 1st of 6 years of secondary, and his brother who is also dyslexic will be in the same position in 18 months, so at that rate I'll need 6 laptops to get the pair of them through secondary 
He will only be using for school work, no gaming.
My dh is Mac obsessed so he's no help and every sales assistant tells me something different - I'm
, please help!
