MOBILE VS. WEB

Mobile vs. Web: on which device do you prefer to document? Basically I'd like to know if there is a preference of device and/or if there are certain workflows you do on a mobile device vs. desktop.  You may be out in the field all day can you do all you need to do on a phone or ipad?

I'm old school, can't get used to mobile platform. I like having multiple tabs/ pages open.

Mobile does have some advantges. I would like that laptops  aren't a hybrid....in other words, I prefer files to apps
