A:AnswerThey aren't as small as they look, they're screwed onto the TV and hold it up well. I'm not sure if Best Buy will send you replacements if you lose them but you can order new legs on Amazon.
A:AnswerThis is a "smart" tv. If you have wifi, you don't need to connect this to your computer. But yes it does have a usb port along with 3 hdmi ports. If you don't have wifi, save a few bucks and don't buy a smart tv. Just make sure you buy one with a usb port. That's what I did before buying this tv. btw, this tv is great.
A:AnswerAs far as I can tell there are a place for jacks and yes extra USB ports to hook up other components definetly depending on how your component comes to be hooked up that will be entirely on your decsion.
