So a buddy of mine was selling his Late 2013 Macbook Pro and without thinking about it, I said, "I'll buy it, bring it over!" He brought it over and it's in great shape, but after I pay him $700 and play around with it, I notice it's an i5 with 4 GB of RAM and has 128 GB of storage.... I suddenly am overcome with buyers remorse. This would be a gift for my wife, so keep that in mind. She's a first grade teacher and doesn't need anything too heavy, just docs and some video editing but on a very low scale. Her [current] laptop is an i5 3000 series with 8 GB of RAM and it's currently running Windows 10, the problem with her laptop is her battery is going out, and her WiFi adapter is dead. So thoughts on my buy?
