I have had this phone for a few weeks now. I also bought the Note 3 a few days ago and tried it out. I took the Note 3 back and went back to the Moto X.
The moto x is awesome. I was comparing pictures I took with the Note 3 and the Moto X on a 27" iMac (calibrated monitor) and I think the Moto is 99% as good as Note 3.
For $99 or $500, either way the Moto X is worth every penny. The note 3 was a great device, no issues at all, screen was beautiful but touch wiz spoils an otherwise good experience.
I also missed my hands free, active display, and always listening features.
The moto x is like owning pure android with sprinkles of awesome added. I love the clean, uncluttered UI.
It's one of the best feeling devices in the hand that I have ever owned. I am an Apple fanboy and switched to the Moto X and I do not miss my iPhone one bit.
I am in love with the Moto X. I may actually keep this one until the Moto X2 is released.
Buy one, you will love it. No need to wait for 4.4 the phone has 4.2.2 but Moto added some of 4.3 into the device without even having 4.3 and is why they are skipping straight to 4.4
Use Google Music myself.
