Oh, and another one. People who are snarky about technology when you've never done a THING to brag about it, force it on them, etc. Last night DH was showing his dad a video of DD at a festival, and FIL, who enjoyed it, thought DH should show his neighbor, who expressed interest in wanting to see the video too. So DH goes over to Neighbor and starts pulling up the video. "Ugh," says the neighbor rolling his eyes and sighing. "I am SO sick of smartphones."
Really? It's not like DH pulled his phone out and was like, "Hey, Neighbor! Look how great my smartphone is! It's so awesome. What kind of phone do you have? What? You still have a flip phone? What is this, 1990? You should really get a smart phone, because of x, xx, and xxx."
We hear SO much PA commentary re: our phones from that side of the family it's unbelievable. Honestly, we don't shove them in peoples' faces, I swear! Last Thanksgiving BIL asked DH to pull up the football score because we were in a place without a TV and radio. DH did, and then went somewhere else to do something. After he left, DH and his dad and uncles all bemoaned smartphones and ragged on them terribly. Nevermind that you just benefited from said smartphone... 
Conversely, going from having a lovely smartphone to a dumber one.

I finally got rid of my user-friendly, easy, simple series of "regular" phones earlier this year, when we renewed our cell contract, and we all got Droids. (We had actually got them a couple years ago, but my own was horrible, a lemon, and I could *not* use the thing, nor did I particularly care, so I got a simple slide phone.) The new Droid was a joy; I sat and played with it for an hour and learned to use it and all its functions very capably. I was a happy gal.
Then, it started to get all wonky on me. It would power down randomly, and take forever to turn itself back on. I decided I would go down to the Cell Co. store and exchange it for the same model, but just then disaster struck. One day early in summer, I was talking to my mom, holding the phone between my ear and shoulder as I was walking out the back door with the dogs, carrying a soda in one hand. As I opened the door and stepped out onto the little cement patio, it fell, and the glass shattered. At that point, I knew it would be pointless to bring it down for exchange, as they would never believe that its problems did not originate when I dropped it. And, STBX had not taken insurance out on the phones, so I was out of luck. Not wanting to spend $$$ on another Droid, I wound up with a refurbished older Blackberry, which I hate. I hate the rolly-ball; I hate that it has only one single alarm setting; I hate that it can store only like ten pictures; I hate that the camera turns itself on via the side button just being carried in my purse; I hate that there is no touch-screen option, even though I used the keyboard way more on the Droid.
As far as typos, I cringe when I see "the" where "they" was intended. My kid teases me about that.
