Is a $300 certified pre-owned MacBook worth buying?
Yes, for the right use case. A Certified Pre-Owned Intel MacBook Air at under $300 from Plug passes a 90+ point inspection and includes a 12-month warranty. For students, light office work, web browsing, and streaming, it's more than enough. For video editing, development, or creative work, budget up to the under-$500 range to get an M1 chip model.
