Being a microkernel system, it is easy to work on things which on other systems need kernel programming (and root priviledges).  Being a capability-based system, it allows transparent virtualization of everything.  This leads to improved security to such a degree, that the user can really trust the computer.  A capability-based system also allows easy monitoring of communication.  Another nice feature is that the user can swap target devices under a running program. I know we are in time to be very picky in the schedule, but should be cool if the speeches are made in different days
