Peering and peering on an exchange are two different things. Peering at an exchange has several benefits other than the simple cost of transit. If you are in a large data center which charges fees for cross connects a single cross connect to an exchange can save you money.
Peering can also be a sales tool. If you buy from a VOIP provider and are peered with them your latency and such will go down. You also have more control over the QOS over that peer. This can be spun into marketing.
Not to toot our own horn but we put together a list of benefits for our IX customers:

> I don't have any quantifiable data on what has happened to IP transit costs over the same period, but for a point comparison I'd say that off the top of my head you can get a 1G CDR on a 10G port from a tier-1 provider in London for approximately the same cost as a 10G port at LINX these days, maybe slightly cheaper.
