hello. I recently bought a mbp 2017 13 inch with touch bar for around 1800. my question is if its worth it to pay an extra 400$ to get the base model 15 inch computer what do you guys think? i have my 13 inch hooked up to an external monitor and it looks just fine. im planning to take this to school everyday for my classes. my only concern is getting my moneys worth. i feel this computer is really expensive and not only that you only have a dual core processor....... the 15 inch has better specs in paper but im wondering how they transfer to real world usage. im planning on using this for adobes creative suite. ( rarely i will be doing video editing) mostly photoshop, indesign , etc so its important for me to have a good screen on the go as well as at the dorms.
