Because names are easier to remember than ip addresses.

What's that got to do with whether the machines have names or
not?

No, you don't.
Windows uses its own peer-to-peer name resolution protocol that
does't require a centralized server which knows the IP<->name
mapping. You can assign IP addresses at random, and still refer
to Windows machines by name (from other windows machines).
Traditionally, Unix won't work that way: it requires a DNS
server than knows the name<->IP mapping. If that mapping is
dynamically created by a dhcp server, then DNS doesn't work
right. I've always thought there ought to be a way to hook the
dhcp server and DNS server together so the DNS server can
update the name<->IP mapping dynamically, but I've never been
able to figure out how to do it.

Doesn't windows have a "fall back" scheme where it just picks
an "unused" IP address and keeps going? Never thought it was a
good idea myself...

The usual reasons, one presumes:
* Laptops/portable computers.
* Easy centralized administration of network configuration.
