The people I've seen using a tablet most expansively are some combination of:
A. people never fully comfortable with a full laptop (meaning they effectively aren't losing much functionality by switching), in fact are gaining from the simplification of features they never really got
B. People doing field work, where a tablet's weight and form factor is strongly superior to a laptop (lighter, can operate standing up easily, etc.)
C. People who like to surf the web in bad, but find using the form factor of a laptop too awkward and a smartphone screen too small
