Certainly, to each their own. I worry far less about how others spend their money than I care about my own spending.Meh . . like I stated before, to each his own. For me it's just another $10/mo with my corporate discount to get an unlimited plan for an iPad on my Verizon account so I just do it and I don't fret over the extra cost since it adds the convenience of not having the device dependent upon any other or having to connect to any WiFi networks other than my own. I'm sure we all can pick on something we perceive as wasteful behavior in someone else . . . spending $10/mo for an iPad data plan is not the only thing I "waste" money on in my life LOL.
In a recent post about whether to have a cellular plan on an Apple Watch, I estimated that I only left home without my iPhone about three times in the past year, for about a half-hour each time. Had I been paying $10/month for a Watch cellular plan, that would have worked out to paying $40 for each of those half-hours. Seems even worse when you convert that to $80/hour. But when paid out at $10/month it's certainly painless. It's not so much a matter of "putting things in perspective" as just how you put them in perspective.
Besides, $10/month pales compared to what many of us pay to own/maintain cars. Considering how little mileage I've put on the thing since February 2020, a limo service would have been much cheaper.
