Hi, all, When rMB just updated, the price of refurbished 2015 rMB also drops a lot. Now it is $929 for the base model (last night it was 1099). So I hesitate. Should I get the new one or refurbished old version? All I want to do with my macbook is just reading pdf, writing paper by Latex, iWork, browsing website, watching movie, listening music....etc. Definitely no heavy work like editing photos, making films, or computer programming. I rarely need to use Matlab but not to run a big program or deal with huge data. I do need portability so rMB is my first choice. But I am not sure if 2015 rMB is enough for me and the new one always looks attractive......Since the price of refurbished 2015 rMB is much lower.....I do need some advice.
