A:Answer From the available information, although the ES6100 will offer compatibility with a traditional standard USB keyboard and mouse, it will not offer support for wireless peripherals. The ES6500 on the other hand will indeed be compatible with both USB and Bluetooth wireless Keyboards and mice, as well as the VG-KBD1500.
Additionally, some Apps will support the Keyboard functionality (Netflix, Youtube, Web Browser to name a few); however, keyboard functionality implementation is solely at the discretion of the app's developer, so not all apps will support this feature.
