Is the XLi an upgraded XL-DC?
NO, XLi is not an upgraded XL-DC. The XLi system is a completely new design with a new microcontroller platform, a new operating system and all new components. However, the XLi has leveraged the modular style of the XL-DC into its core, which leverages many of the XL-DC plug-in card capabilities. In essence, XLi maintained the bloodline of the legendary XL-DC with all the modern technology innovations and advances incorporated.
