OS on embedded or NOT?

[Ari]

Project:
An Arm7 with 3 UARTs.
Two of the UARTs are for communicatinng with network nodes.
the other one is used to communicate with another chip useing serial comm.

At this time I am using a simple main loop, no OS.
My compiler is Keil and i can use OS but I don’t see any reason for doing so.

I was wondering if anyone can give me some hints on why would anyone use OS on a embedded device.

Would you use OS for the above project?

thanks

Ari
