[cantankerous]

I find it really impressive that a company can roll out incremental changes to 100,000 devices in a week. I wonder if the author somehow got it mixed up and the updates to each weekly device aren't necessarily a week old. It's just rolling updates hitting every batch every week. That would make a little more sense. I think some other people have said in the comments that some changes just wouldn't fit into a week's time span. I suppose it would also make sense if all the changes were somehow tiny in nature.
