3.那個看來是商用版的保固。家用版的現在除了Mail-In就是 Permium (~= NBD + ProSupprt) 商用版則是 Mail-In / Basic(NBD) / Pro Support / Pro Support Plus。同一台機型如果你是買"家用版"(for Home),就應該只會出現 Premium, 選"商用版"(for Work), 就應該只會出現 Basic/ Pro Support / Pro Support Plus
另外你沒列出來的保固項目(中高階機器才有的)還包含了
4.Keep Your Hard Drive, 就如果 HDD 爛了,選這個選項後 DELL 就只會寄新的HDD來,不會收走你的舊的壞掉的那顆 (因為理論上有可能被有人心士撈資料出來,自己保存就自己處理)
