For me it needs to have a good library of math functions and a tactile input interface, not being bigger than 165mm x 85mm (see http://www.hpmuseum.org/forum/thread-9646.html ). For example graphing calculators are not pocket ones in my opinion.

Calculator apps for devices with touchscreen keyboards are only useful for emergencies since the keyboard is not tactile. (or on large screens, like 8'')
