My gal wants one because she doesn't like to play games on the PC and some of the new titles will only be released on the new consoles (and PC). I like the idea that you can stream your Xbox One games to your Windows 10 PC. When she's watching TV I can still play Xbox One games.
I just bought a little box called the
Steam Link. It lets you play your PC games on your TV.
She's 55 and I'm 68. None of our friends play video games but her son and my daughter and grandson do. I just friended a buddy's grandson on Steam.
I hope to snatch one. The Xbox One alone is presently going for $349.99 USD.
