What electronic device or gadget would you miss the most?

...if it just wasn't there anymore - as in, can never be replaced - ever!
Something at home maybe? at work? in the car?

(why do I guess that mobile/cell phone will be the most?)

You can count things like washing machines etc
Oh - and why?
Update: EDIT
Jj, pretty close with your a to NASB.
