Cars or Smartphones/Tablets
I spend enough time on computer and on the internet at home! Cars are fun if they have enough performance - and I enjoy driving! Slow drivers are like slow phones! I just need a phone for emergency or to contact someone in a hurry or send a less hurried text! So Tablets and Smartphones are no-brainers for me, but I'd be a bit lost without my car!
I even don't use or have a SatNav, as I prefer to find my own way to places, and there's always Google Maps if I get stuck! So, yes, I think the novelty will wear off with Tablets though I might think differently if I was a regular train user for lengthier trips! Smartphones are just too complicated for me to be bothered with. Simplicity and speed are all I need with a phone or a car!
The ongoing high cost of hi-tech electronics where things rarely manage to reach five years of use, and mobile services continue to be (mostly!) enormously expensive are other big factors in things over time!
