As applies to me --

I have never tweated
I don't own a Blu-Ray player
I don't own a kindle...I still read books
Half the crap in my car--Sirius radio, Sync, etc.--I don't use and don't miss
I don't have an iPod (except on iPhone, never use it)
I don't own a Wii or Xbox...don't play video games at all (I read books)
I don't have GPS (except on iPhone, have used it a couple times)
I don't have a Netflix account...I go to theatres

If time were not an issue, I'd run out today & get an Xbox or PS2.  But, there's such a tendency to get sucked into today's games it would eat away at my book, comic & movie time.

I only got a smart phone in Dec 2010.  Some family issues & being away from work caused to me to get an iPhone & I'm not sorry I did. 

I don't think I'll ever get a Kindle or something similar.
