NO, IT IS NOT AN OMNI-TOOL. WRONG UNIVERSE, DAMMIT.

Every Device Is A Swiss Army Knife/Magic Tool: The ubiquitous nanolathe is pretty much the poster child for these two: basically, it’s a bunch of processors, a future-iPad-equivalent, a complete universal network interface, a pocket-sized nanofac, and a bunch of miniaturized nanomanipulators, vector effectors, and a few other tools built into one handy gauntlet-style package that still permits full hand use and is wearable with most clothing.  It can make a wide variety of useful objects (described by software recipes) on the fly, interface with, analyze, debug, modify, and repair just about anything recognizable (including lifeforms), operate as a remote control for even the most complex devices, scan for any number of things, perform a wide variety of computational tasks, let you communicate in a variety of ways, operate as part of your personal-area network, and chill drinks.

Also, it runs apps.  And there is almost certainly an app for that.
