problem is, among the items you enumerated, phones (usually) are the cheapest (not comparing flagship phones here, you can get good-ish entry level phone at 150-200 USD (I use one) and goodish laptops start around 300 (and even then it is mostly underpowered chrmoebooks, many of of which are not good), tablets (entry level) start at about the same prize of phones, but for a given prize, you would get other specs lower (they have to cut cost somewhwere, and larger screen costs more). Now, these tablets can serve as a carrier for information, but that would not be the most ideal solution.
