Samsung Gear VR for my phone
No it's not perfect, but for $99 and the fact it uses my cellphone as the screen is pretty freaking cool! I really thought nobody in my family would think it's cool, but I didn't even get time to play with it on Christmas day! My parents were exploring France in 360-degrees, and my wife was exploring the Chicago Skyline! Hahaha, yes the resolution of my phone means I get a 'screen door' effect, but it was an awesome Christmas gift especially since I was able to share the fun with my whole family (they usually never comprehend the various techy gifts I ask for)
Oh, and I also got a Samsung Smarthub and a few sensors so I can turn my home into a smart-house
