I have a 2.8 GHz 16GB 512GB SSD 13" Macbook Pro (Mid-2014). I can get $720 for it. Runs great but starting to run hot on some webpages, it only has 273 Battery Cycles on it. Should I trade in the MacBook Pro for a new MacBook Air with 16GB and 512GB too bring the price down around $1,300 after AppleCare+? I am a graduate student so the MacBook Pro 13" (2018) might be too pricey around $2000. Workload is mostly word, excel, safari, light photo editing in photos, and email. Any input would be appreciated, I'm torn... Thanks.
