OK they can share the sourcing of their download between various computers but I still can't see it being as efficient as a straight download at full speed from a fast server.

Instead, that's exactly why it works so well.
For example. That video I mentioned above, put the server that hosted it originally down very quickly, after it was linked from Digg (and some other site).
Instead, my mirror, hosted in a not so powerfull (compared to some other hosts), keeped up without a problem with the increasing demand.
Whit Torrent, even a small, single user, with limited resource, can host a very popular and larged sized files, with not much worries. The Tracker has very limited resource hit on the server, and the compound bandwidth offered by a swarm of PC with even low upload bandwidth soon build a very powerfull serving platform. The more popular the file will be, the more faster everyone will download.
