I'm usually not in favor of these large mergers since they reduce the number of competing companies, but for anyone more knowledge about the US cellular industry, would this merger actually be in the interests of consumers? ATT and Verizon are such behemoths already, would a Sprint/T-Mobile merger bring more competition to the market? Also, why is Deutsche Telekom so keen on selling off T-Mobile?
