I bought my 6 on launch day. I was originally on the fence about getting the 6 or 6 plus. Today I bought a 6 plus with the intent of switching back and forth. Now I am wondering if I should sell my original 6 or keep it. Not as a spare but literally pop the sim for whatever phone I am feeling that day. Keep in mind that I do know that I have a problem. I am an addict. I normally swap phones like every 6 months. I buy more cases than a person should have. I also like both of these phones and if there was a 6S model that was out today... I would have just bought that.
