In this upcoming update, you will be able to use your own mouse on a virtual PC screen in game. Although most of this stuff will be unavailable, there will be a time where you can use the PCs to find what your looking for, as well as alot of misc. stuff.
By misc. stuff I mean info, Skill Points, or some other thing. Of course, the ACTUAL menu will be disabled until you select "Shut Down" or anything the lets you log off the Computer. Well, time to work.
