There are many situations where running BGP doesn't take a big router, because the particular application only needs a few routes. Second, the simple answer is "multihoming". Most frequently, this means that you are multihoming to different providers. There can be, however, very valid reasons to use BGP when you are connected to multiple POPs of the same provider, and want to control load distribution over the set of POPs. There are a few special cases where you might run BGP when you only have a single provider connection, such as announcing routes to a 2547 VPN, and neither static nor IGP routing is appropriate between the CE and PE.
