When I worked in the wireless industry (about 9 months ago) the income for the actual company wasn't that great. It took the company I worked for a little over a year to actually start making profit on an average customer. Even when I worked for the industry I tried not to buy their kool-aid, but this figure I actually believed since I worked for a smaller local company who's owners and executives were quite open and, at times, honestly blunt with us.
There's a key difference here, mate:
Commander: Go to Iraq, soldier! Soldier: No sir, I don't want to. Commander: Then get out of the military.
RIAA: Hi lawyer, would you like to sue people for us? Lawyer: No, I only accept legitimate cases. RIAA: Okay then.
Lawyers can turn down cases and keep their job.
So the Law profession is the exact opposite of every other industry? Every employer I've heard of fires you when you tell your boss you refuse to do what the company has set forth as policy.
You can safely bet that if I tell my boss that I'm going to turn down supporting a new application because I don't believe in promoting horrible products, I'd be out the door by lunch.
God schmod. I want my monkey man!
that seems a bit redundant...
Numeric stability is probably not all that important when you're guessing.
