In the defense of old people, I just turned 75 and for the record, first got HD 10 years ago on one HD RPTV in 2003, and HD on all four of my new flat-panel displays when I moved into my new home in 2008. No more vacuum tubes for me. So long, see ya!
I'm 65 and I bought a Sharp Aquas 37" HD set in 2008, it's still going. Two years later I bought a 24" Sharp 720 from Sears & died two years later.
