Nexus 5 Unlocked....A Good Idea?

[MAV88]

I am just curious what the benefits are, if any, in buying an unlocked phone. I put my order in for the Nexus 5 through the Play store the other day and this will be my first unlocked handset.

I also am wondering why Google has opted to offer this phone unlocked.

no contract, can move to some different carriers if you choose
since no contract you can upgrade to the newest nexus every year for very little if you sell your old and buy your new
