First you had the transparent PDA he used to make his point (emblazoned with the LG logo). Said device let the fictional genius hijack other devices and systems on demand.

speaking as a future IT guy, in which security will be one part of my job, i hope that is one gadget that does not come true. though it would make a good smartphone.

Really, for the suit we're mainly held back by a lack of decent power in a small enough form factor (read: compact, light, massive capacity or generation). The rest would be easy, once we have the ability to power it.
