Frequently Asked Questions

5 questions

  1. The 15-inch MacBook Air is objectively better for coding because the larger 15.3-inch screen allows developers to see more code simultaneously—typically 40-50 lines of code versus 25-30 on the 13-inch. This reduces scrolling fatigue and improves productivity by an estimated 15-20% during long development sessions. However, the 13-inch works adequately if you use external displays or frequent terminal-only workflows.
