高盛分析师团队的核心逻辑是：内存芯片成本大幅上涨导致智能手机BOM成本显著垫高，对于价格敏感的入门级市场，这几乎是毁灭性打击。在新兴市场，消费者对价格极为敏感。一旦售价低于200美元的入门机型因成本压力而涨价，需求往往会迅速消失。高盛预测，2025至2027年间，全球入门级手机销量将以年复合增长率-4%持续萎缩，其市占率将从2024年的44%下滑至2027年的40%。

You may have encountered keyboards with an optional lift at the back of the board, raising the top keys higher than the space bar. Every set of hands is different, but for most people, pulling the backs of the hands towards the forearms increases strain. Negative tilt has the opposite effect by sloping in the other direction, lowering the top number keys while raising the edge with the spacebar. Many Alice and some split keyboards offer an optional negative tilt. I found it was more comfortable to enable that feature when I’m standing, and I preferred to have the keys flat when sat at my desk.
