My next MacBook Air will have 16 GB of RAM (up from 8 GB), 1 TB of storage (of from 512 GB), all this in a 15 inch configuration. I decided to give my previous 2020 M1 MacBook Air to Apple for a 580 CAN$ credit, plus the 200$ credit for the “back to school” promotion. And… 1500 CAN$ of Apple Store credit, thanks to my job bonuses! This could be the cheapest upgrade ever!
