I'm a student and have a small business that allows me to get back paid tax/vat. So I can get the 13" for 1550 and the 15" for 2050. (Euros and 256gb version). I'm having doubts on which version to get. Do you think the 15" inch is money better spend? The quad core i7 and 16gb seems like quite an upgrade and if I'm gonna spend this amount of money I'll better do it the right way. I'm not a heavy user so I don't know if I need the extra specs. But I rather have my dream machine than spend 1500 on something that works 'half' after 4 years. Thanks!
