Three Key Upgrades that Would Make the M4 MacBook Air My Dream Laptop

The author expresses their desire for three specific improvements in the upcoming M4 MacBook Air refresh, including a display brightness of 600 nits (up from 500), better thermal performance to avoid throttling during moderate use, and inclusion of the Center Stage camera system as seen on other recent Apple devices. While noting that they would be satisfied with an incremental spec bump given the device's focus on portability, the author argues these changes would make for a significantly more compelling overall package and justify upgrading from their current M2 MacBook Air to a larger 15-inch model.
