DW and I usually just bring our phones.  She sometimes brings her kindle if she's in the middle of a good e-book.  Our boys bring their Nintendo DS systems. That's usually it. Once we're set up, the general rule is no electronics (TV, DVD, DS) unless it's raining, although sometimes we'll put on a movie for them in the evening after dinner once it starts getting dark early and cold. 

We almost always bring the boys' bikes and we have a lot of board games and outdoor toys to keep everyone busy.

My Kindle goes EVERYWHERE with me. DH has to have the TV/DVD player....but he actually rarely watches it when camping. It's just his security blanket, I guess. If we stay at a private campground, I bring my laptop. Heck, free wifi, why not?
We, too, have a stack of card and board games for the inclement weather. We therefore play a lot of cards and board games when we camp, because inclement weather follows us everywhere.  ;D
I bring a craft (or two) to do. And a long PUP to-do list for DH.

Looks like it's going to be 2-smart phones, 3 tablets-1-DW, 2-Kids, 1-tv/dvd with satellite. 1-Phones has a hot spot for wifi on tablets if 4G service is there to pick it up.

2 iphones, PUP has DVD player, usually no laptops or kindles. Have kindles, but still like the feel of a book and they seem to be longer than when on kindle.

The TV/DVD player stay in the camper, but I bring a tote of videos for the G'kids, my cell phone and Kindle.

We now have three smartphones, three MP3 players, two external speaker systems, and sometimes my laptop for work.
The kids use the smart phones to play team Minecraft at night, we sometimes use an MP3 player for background music.

Well "everyone" has their own reason/argument for everything they do/dont do.

As for me and Kathy. We both have bad sinus/allergy issues.  We dont spend a lot of time outside, even when camping.  So it really depends on "who" we are camping with, as to what devices we take.

When we go to Branson, we usually just take the laptop (and cellphones) so we can keep up to date with anything going in around the Branson area.

When we go to our fav CG. We take laptop, cellphones, TV, sat dish.  There really is not much to do there except walk the park. No nature trails.  We cant usually handle a campfire due to allergies. Smoke from neighbors fires usually keeps us indoors at night.  HOWEVER, with me being a late night owl. I spend some time outdoors after everyone else goes nighty night. I walk around the park or just sit outside and listen to nature. (After the fire smoke clears).

Nothing "smart" except our brains! we try to unplug as much as possible when camping -basic cell phones or walkie talkies come in handy

That's fun. What's your furthest contact so far?
When I was a kid, a neighbor had a 100+ foot tower with a beam antenna! It looked like a high-tension tower!
