I had a black and white one when I lived at my parent's place, 20 some years ago.
My ex-wife had one - that's back in the 90s.
And today, my wife and I just received our first TV for the bedroom.
Apparently, and according to the box, TV's are now smart - which is kind of funny me considering how dumb the stuff on TV is.
Things sure have changed. That thing hooks up to the internet, it downloads software and updates itself. Connexions used to have no secrets for me - it was all so intuitive. Now those things have so many different formats of connexions available, I almost feel like my dad when he tried to use an ATM for the first time...
We have no intention of getting regular cable TV - we plan on using this thing to watch stuff on Netflix and such and/or to hook it up to a computer to act as a glorified monitor to watch series and movies.
40 inches will be quite a move up from the MacBook's 13 inches screen. :)
