I have Sonic at home, and applaud this log deletion policy. There's only one thing that bothers me about Sonic, the marketing vs reality of DSL.
Their marketing: $39.95/m for speeds up to 20Mbps
Their reality: ~$50/m for ~8Mbps
Now I continue to pay despite this discrepancy. I just wish there was more of an 'under-promise, over-deliver' mindset in their marketing dept.
