My wife desperately needs a new MacBook Pro. Her 2011 is on its last leg and just isn't cutting it anymore. I have the opportunity to buy two different machines here locally from an authorized Apple seller. He has a 2015 refurbished MacBook Pro directly from Apple sealed in the box (Mid 2015 512GB 2.8GHz 16GB RAM) and a new 2018 (2.6, 1TB, 32GB RAM). He's asking $1800 for the 2015 and $2250 for the 2018. I know the seller and I get a discount from him as I've purchased from him many times in the past and we are friends. My wife would use both machines for video editing, photo editing, and everything else you'd use a Laptop for. She would really like to have the 15" model as she looked at the 13" and would like the larger screen. She likes the keyboard on either and doesn't really have a preference. Outside of price would I be insane to get her the 2015 model? Just looking for some opinions here as I consider this place to be where to go for these types of questions. I have no doubt that the 2015 is a great machine (I have one but don't do nearly the heavy work she does on a computer), but my concern is about the longevity of it. Its approaching 5 years old and I'm just wondering if its a laptop that she will be able to keep a while. Plus the specs offered on the 2018 are very nice (more storage, more RAM). Any thoughts? Thank you in advance.
