Getting involved with the work back home has also become so much easier, faster, and cheaper than it used to be.
My wife and I are in Europe several times a year for one to three weeks at a time. In the 90's, before cellular companies were large enough to have a global footprint, I would often return with a $2,000 - $3,000 phone bill from spending time on the phone with issues here. No that I can roam globally without any change to my cellular plan/bill, and can remote control from anywhere, there is basically no financial downside to working while on vacation.
Just the stress of family staring at you while you continue to say "one more minute, please".
Of course, now, a tablet on my lap in the passenger seat allows me to take care of these things without delaying individual event while on vacation.
