Yes, I did after about 4 or 5 days after launch day. I am an active runner and father of two small children. The big screen was nice, but my life has far too many opportunities to drop my phone if I can't have two hands on it. I need solid one handed texting comfort and a smaller size for 4+ mile runs. The 6 is just a better fit for me. I do like the extra screen space on the 6, going from a 5S. It's perfect now I'd say.
