iTwin

This is interesting - - iTwin.  The iTwin is a tiny device like a USB stick with two ends.  It splits in the middle, whereupon you plug one end into your desktop (PC or Mac) and carry the other end around with you.  Wherever you then find yourself in the world, you can plug the portable end of your iTwin into any Internet-connected computer of either type and gain full, secure access to your office machine.
