I can't say I'm looking forward to it, usage isn't that high especially considering that I'm on the new WoW expansion beta and have been patching it:
Uptime: 10 days, 10:11:48
Data Transferred (Sent/Received) [GB/GB]: 1.99 / 9.73
But a lot of this is at peak times so quite likely I'll trip STM every so often, even if my usage is less that 30GB/month downstream which is hardly excessive especially for an XL customer.
