I am in the process of choosing between a 2012 june refurbished macbook pro or the new macbook pro with USB 3.0 The reason being, the refurbished is way cheaper, and right now the specs are pretty good. However I realized that USB 3.0 is becoming quite popular and I dont want my computer to become outdated so quickly. (no, a USB alone wont outdate it, but USBs are used quite often) I remembered when they introduced USB 2.0, it took quite a few years before it became the standard. So assuming that this macbook is gonna last another 6 years. Do you think I will be ok without USB 3.0? Thanks guys so much for your input.
