Bricklayers may not use tablets for work, but I bet they use smartphones a ton, and not just as communication devices. I know I use mine constantly when doing "real world" workâmy laptop's a much worse camera, flashlight, level, and measurement device than my phone, and that's just the things it's worse at without even factoring in portability (which would include almost everything else one might want to use an Internet-connected device for on a job site, which a laptop would do alright at except that it's huge compared to a phone).
[EDIT] "but why's a camera important to construction work?" want to get a usable estimate of how much tile you need for a room in about 5 seconds flat, recorded for later use? Snap a photo of the floor with the 4' by 8' plywood exposed. Done, you can walk away now. Ditto drywall if the studs are exposed and follow standard spacing, and so on.
