Fellow designers please help... Should I switch to a higher storage or a 1tb external hard drive is good for me? I bought **base model of the 15inch rmbp. Is this enough for all the programs I'm going to use if I buy a 1tb hard drive to store files for school? I'm planning to use this laptop for 5 years. Please don't say "oh you can't use a laptop for that long etc..." Unfortunately I don't have the luxury to drop $2000 on a new laptop every 2 years like people do here. Starting school this year... I'm ***NOT*** a gamer.
