Do you have ALL of the below?
1) Apple Watch
2) iPhone (or iPod touch)
3) iPad
4) MacBook or desktop Mac
and
5) Apple TV?
If so, how has this affected your life?
No, yes, yes (although my daughter has claimed ownership of it,) yes, and yes.
I am a Pebble fan, both for the long battery life and cheaper price.
I just upgraded to the 6S. Before that, I had a 4S, before that a 3G. So it'll probably be the 7S or 8 before I upgrade again.
Got an original iPad from a coworker - he won it, didn't want it, wanted a desktop computer, I had a spare PC. It was a few months before the iPad 2 came out. I used it fairly often, and was able to nearly replace my laptop with it. Then I changed jobs, which required me to have a work-provided laptop for work uses, and upgraded to the iPad Air when it came out (Target extreme trade-in special,) and now my daughter uses the iPad.
I've had Macs as my primary personal machines since 2003. Haven't bought a brand new Mac since the Intel switch (original MacBook Pro, fully loaded.) I'm currently on a bought-used-a-couple-months-ago 2011 21.5" iMac. My wife has a 2013 MacBook Air (bought new - the first new Mac in our house since 2006.)
For a while, I was a "cable cutter," using only broadcast HTDTV and internet video services, so the AppleTV (gen 3) was my primary internet-video device. It still sees regular use, but recently got cable TV+internet (DSL was slow, and getting more unreliable every month,) so it's no longer my primary viewing device.
Having the "matched vendors" for phone, computer, and streaming device is nice. While I had my work laptop (Windows,) I tried to use it for personal uses too, but it wasn't as convenient. I also had a work-provided phone, but kept my personal iPhone 4S because the seamlessness of it was easier.
