what interesting technological invention would you want that doesn't directly result in you getting immortality, money or sex?
Id want that helmet from Die Another Day that lets you become rested in under half an hour instead of 8 hours.
I think that helmet - if we're thinking of the same thing - is more about overwriting your memories and turning you into someone else in mind and well as body. That's 2spooky for me.
I'd go with Iron Man suit.

all from one little device that goes inside of your skull.
Those are love cabins you assface.
You go in there and fuck.
Pretty cozy to be truthful.
High end contact lenses that as as VR/augmented reality. Lag free interface to a system equivalent to twice the power of a dual 5960k/3 way SLI Titans in the size of a chip implanted in say your chest or something(to avoid accidental damage). Chips in your hands act as input devices or use direct brain interfaces. Yada yada.
Basically a super computer AR/VR/HUD in your eye. GPS, games, public info, notifications, muh waifu. Would be cool.
