If you ever see someone with their laptop open in one hand and (optionally) carrying their AC adapter with the other, heading off to a meeting room, that's what iPad is for.
If you see a doctor walking in to the office, greeting you, then turning their back to you to clack something into a desktop facing the wall, that's what an iPad is for.
If you see a delivery person or home-service person (plumber, contractor, arborist, lawn mower) or even a cop sit in their car for several minutes as you look at them wondering what the hell they are doing in there for so long, that's what an iPad is for.
When you see a realtor have their laptop setup and using some clunky interface to hook into as you gather around leaning over a kitchen island to see some number or other, that's what an iPad is for.
It's not for coding sessions or writing novels or anything crazy like that. It's for plugging into a projector to do a presentation; it's for handing to you to sign after it's been used to swipe your credit card for a purchase, or when you receive a delivery; it's for your doctor showing you a test result without you getting out of your chair or bed.
Give it a few years, then it'll look less like a toy and more like the Jetsons.
