Hey good afternoon, I'm looking at a couple of options: Refurbished 13.3-inch MacBook Air 1.6GHz Dual-core Intel Core i5 https://www.apple.com/shop/product/...nch-macbook-air-16ghz-dual-core-intel-core-i5 Refurbished 13.3-inch MacBook Pro 2.5GHz Dual-core Intel i5 https://www.apple.com/shop/product/...133-inch-macBook-Pro-25ghz-Dual-core-Intel-i5 The Chat assistant has let me know that both devices will come equipped with El Capitan. I also intend to purchase a 1TB external hard drive to store photos and do backups. The Macbook Pro is from June 2012, the Air is June 2016. Would the 4 years of technology advancement be worth the extra $50 and way less storage space for the Air? Is that .9 ghz really that big of a deal? I am working from home as a freelance writer. I don't do much with photo or video. I won't be storing movies on the computer. Would I be required to purchase the Thunderbolt adapter? That might help make my decision, I like having all the ports built into the laptop. What else will be helpful to know? The price difference isn't a big deal, I'm just not sure if the functionality is all that different or if I'm getting a better device for my needs one way or the other. Thanks for your help!
