Only BA is relatively good.
AMZN face tough competition in almost all areas. It cannot
make serious money for quite a while.
VZ and ATT both will see big issue ahead because more and more
people go with prepaid and using wifi(or data connection) to
make VOIP calls. I even found VOIP most of time has better voice quality.
So, their margin will be lower and lower.
