They break up broadcast domains, also makes adding users easier. Also lets you segment access to resources a lot easier. For example, you have a new person you need to add to a department, but they have to be put far away from the department physically. If you only had a hub, you would have to plug them in elsewhere, and mess with everything on the other end. VLAN, just drop them in anywhere physically, then make them a member of the department's VLAN, and you will won't have to go through all the extra trouble.

Some environments have Lab and Corporate networks. The Lab network is usually for test equipment that can potentially go crazy, but at worst it should only mess up the lab network while leaving the corporate network intact.
The easiest way of implementing this sort of segregation is to use VLANs.

VLANs aren't bridges are. VLANs are used lin LANs for corparations of the web so they can still have a secure LAN type network even though they are located in different parts of the world.
