谷歌的Nexus 9并没能像他们的Nexus 7一样打出本垒打。它的质量略显粗糙，但价格却有了明显上升。除此之外，还不是所有软件都可以在谷歌最新的安卓5.0 Lollipop 64位系统中顺畅运行。
不论如何，HTC给我们带来了一台十分不错的平板，尽管主要在机身质量上用户需要降低要求。Tegra K1的性能十分惊人，它的屏幕尽管有些位置可以看到些光晕，但仍然十分绚丽。另外，它的扬声器非常优秀。
但是，K1的性能在高负载下会受到明显的降频的影响，因此Nvidia的Shield tablet可能仍然是游戏玩家的最佳选择。它并没有这类的问题。而2GB的工作内存在长时间使用中可能会成为系统的瓶颈。但是，这仅限于64位版的安卓5.0。我们在Nexus 5（32位）的测试中并没有遇到这样的情况。它的存储空间也无法扩展。因此我们希望能够有更大容量的版本可供选择。
我们建议需要有超长电池续航，64位系统支持，和强劲性能的平板的用户，一定要将谷歌Nexus 9纳入考虑范围。
