Unlocked Phones.....

[OrlandoSGM]

My phones are going on two years old now, and they are showing their age. Poor battery life, scratches, etc.

I am on T-Mobile and think their service is really good. I do not like their new phone marketing. I'd rather sign a two year agreement and get my phones subsidized! With that in mind, I'm looking to purchase an unlocked phone. I know of three that are on the market or will be soon:

1. Nexus 5
2. Motrorola Moto X
   
3. One-Plus One (scheduled to come out any day)

Has anyone had any experience with any of these or other unlocked phones? I like the specs for the One-plus One a bunch, especially for the cost!
