當你想確定使用者在產品詳細資料頁面上的行為，是否會因為裝置類型而有所不同時，應該提取哪種報表？

The "Pages and screens" report (網頁和畫面報表) in Google Analytics 4 (GA4) is the most appropriate choice because it allows you to analyze user behavior on specific pages, such as product detail pages. You can then apply a secondary dimension for "Device category" to segment the data and observe how engagement metrics (like views, average engagement time, and conversions) differ across desktop, mobile, and tablet users for that particular page. The "Tech details" report (技術詳情報表) focuses on browser, operating system, and device model, which is too granular for a general device type comparison. The "Events" report (事件報表) tracks user interactions but doesn't directly show page-level behavior segmented by device type. The "User acquisition" report (獲取新客報表) focuses on how users arrive at your site, not their behavior on specific pages once they are there.
