They aren't very draconian about overages — they won't shut you down if you go over.
$0.10/GB if purchased in advance, $0.15 retrospectively.
Also, if you have multiple linodes your bandwidth is pooled.

Their traffic allotment is fairly generous compared to comparable services. Sure, if you compare it to something like 1and1 with 'unlimited' for $12, maybe not, but you don't get the same control and reliability for something like that. If you compare it to how much it would cost to serve the same requests on Amazon S3, it's much cheaper.

Unless you use it as a file server that's not too little actually
200GB of traffic included seemed good at the time, but it doesn't already. I'm seeing (and using) more offers lately that have much more traffic included.
