As I posted most of these devices can use bluetooth keyboards, touchpads and a mouse. Mine has a slot for a mini sd card as well as a usb port. You can connect hard drives and other hardware.
Mrs p6 and I like to watch A&E’s ‘Longmire’ in delay. Over Comcast it can become pixelated. Over the Infinitec that doesn’t happen. Both are in HD 1080 resolution.
BTW I have a Rasberry Pi but haven’t played with it much.
After using the wii (w/usb keyboard attached), we found that a laptop (w/hdmi) is great plugged into the big tv.
