Best Practices for VLANing small network (sub 15 PCs)

So for small, individual sites (think less than 15 PCs) is it really a benefit to VLAN the Network other than for VoIP phones?

I see lots of people VLANing off Printers, Servers, and Workstations in like a 10 user network. What is the primary benefit? All the workstations have to talk to the server and printers. Isn’t this just causing more management on the IT end without providing much of a benefit?
