联想V821应该是V520的升级版。升级的重点在摄像头和屏幕,但在内存方面又有所缩水。并且与V520的活泼可爱不同,V821生就一副稳重的面孔,外表绝不张扬,内里却依然好动、好闹,多媒体功能一个没少。所以我们说它是“爱玩爱闹的谦谦君子”。 Lenovo V821 V520 should be an upgraded version. Upgrade focus on the camera and screen, but in memory has shrunk. And V520 lively and lovely different, V821 born a steady face, the appearance is not assertive, the inside is still active, fun, multimedia features a little less. So we say it is “modest gentleman who loves playing love”.
