Oh, I understand there are differences and like many, I'm curious to see the direction Google/Motorola are headed but when you boil it down, they're really not that different and we're talking about a 1+ year old device.
- .1" smaller screen size is insignificant. On screen buttons--purely subjective preference. I prefer 'em as well but many don't.
- US versions of S3 had 2 GB RAM
- Prettier??? Beauty is in the eye of the beholder. I personally don't like the looks of recent Samsung offerings but have seen plenty of others who disagree. I also don't find the Moto X particularly stunning and am not sure about the hump along the rear spine.
- Price. Color me incredibly skeptical on this front. The only devices the have broken the typical pricing scheme are the Nexus (off contract) and I'm personally not getting a 'budget' vibe from all the leaks/rumors/speculation--certainly hope I'm wrong. I don't see Moto positioning themselves as the 'affordable' brand, just my opinion.
- Updates. Again, completely dependent upon there being an unlocked version available via Google Play. I'd guess most versions of the Moto X will be carrier branded and they're going to be subjected to the same problems we see on all carrier branded phones.
I'm sorry but I just think many of you are being blindly optimistic about this device--"if it has XYZ features, AND it gets quick updates, AND is only cost $X, then it'll be awesome!" Where's the precedent to expect all of this to actually happen, especially with Moto? When was the last time the stars aligned to give us everything we hoped for in a device? Heck, the jubilation over the GPE versions of the One and S4 was squashed to a certain degree when it was revealed that Google would be responsible for the updates but rather the manufacturers.
