戴尔发布了最新的顶级PC—XPS420，它是第一款整合了Windows SideShow显示器的台式机，主要用于在vista无法表达时显示PC运行时的重要信息。该显示器位于机箱顶端，所以如果您把机箱放在显示器旁边的话就不太容易看到，因此这台机器适合地上。以下是该PC的详细信息：

    * Intel processors, up to Core 2 Extreme 3 GHz
    * vista Home Premium or Ultimate
    * Up to 4 GB RAM
    * Up to 2 terabyte RAID hard drives
    * Up to a Blu-Ray drive and dual layer DVD R/W drives
    * Up to 768MB nVidia GeForce 8800 GTX
    * Available AGEIA® PhysX® physics accelerator
    * Up to Sound Blaster X-Fi Xtreme Music audio (cannot order advanced audio and the PhysX card, presumably due to a lack of expansion slots)
    * Available ATI Theater 650 PRO Combo TV Tuner with up to Gyroscopic Remote and Xcelerator
    * Comes with Dell Bluetooth Wireless Media Hub + Bluetooth Keyboard and Mouse
    * 802.11b/g wifi card (but no available 802.11n)
    * Up to Bose Companion 3 Series II Multimedia Speaker System
    * Free 10GB DataSafe Online Backup for 1 Year

    从配置上看已经是顶级了，而且还有无线网卡，这也是台式机无线化的先驱者。在国内暂时没有什么消息，请关注我们的后续报道。
