I suppose that I'm one of the few archaic luddites who agrees with the sentiment behind the OPs feelings on the subject.
You're not.
DW and I keep ours with us most of the time because sometimes we will split up for part of day (ie. last trip I did the KTTK tour while she went to The Dolphin for a spa day). And now Disney has made it so you really need them, IF you want to toy with your FP+ and ADRs all day.
What bugs me about all the cellphone/ipad/whatever usage is all the awesome stuff people are missing while they bury their heads in the devices. WDW might as well just put attractions in big warehouses with no theming because a lot of folks are missing the whole thing.
Especially when it blocks other guests views of the parade/show etc.
