Should a new LAN be entirely wireless?

There are also about two dozen Windows PCs throughout to provide catalog and Internet access. I was surprised to notice that all of these public access machines are connected wirelessly, using D-Link expansion cards. The Ethernet jacks on the backs of the machines aren't connected to anything. I'd understand networking the machines wirelessly in an old building, to save the cost of pulling Cat 5. However, this is a brand new building built just for this library, and there is obviously room for cables — the power cords for the computers are coming out of the floors. I would think the low bandwidth of wireless, coupled with the headache of troubleshooting interference and performance issues, would rule out a deploying wireless like this — it's relatively easy to wire a brand new building. I'd also think Cat 5 is more future-proof. Obviously library staff disagreed. How do you think the advantages of wireless would outweigh the disadvantages in a setting such as this?"
