@blr_p : Well to be honest, I just bought the X cause I believe in the thing that it is a device which I loved from first sight, if I got the S5 or any phone I just would not be able to forget it. So bought it. Also, TouchWiz has NOT changed, so that was a no go.
@Jambumali : Thanks mate.
This is my very brief statement on the X and the experience coming from an S4 i9500.
The phone is compact, near perfect size for a mobile phone, my thumb can reach the top left corner and bottom right corner, that's great. Good ergonomics. However there was a big confusion, I bought the White one, and just by looking at the photos I thought that rear panel had some kind of grip as there are dotted texture on it, but there is no grip, at all. The back is very slippery, the dotted textured is coded inside somehow. So I believe I should have gone for the Black or the Blue, I wanted one with that soft touch feel! Whatever!
Other than the size, I am loving it's performance. I won't play GTA V or Watch Dogs on it, so I don't really know what's the hardware, I think it's a Dual Core CPU, don't care. The optimization is at it's best. It's been 48 hours since I have received, played with it extensively, Gravity Box and Xposed along with Faux kernel is already been tweaked a lot, I mean I tried to make it bad

but this thing does not slow down in any case. Coming from an S4, this thing just flies. Honestly it will feel like it has some Octa core CPU in it! Near Stock Android experience is clean, smooth (without any tweaks, and if you use Performance governor as I am using right now it is as smooth as iOS, yeah you heard that right. Even with default governor it's pretty near to the fluidity of iOS) and awesome. Samsung definitely deserves a reward to crap up TouchWiz that bad, God knows how!
It has fantastic call quality, the best in a long while, and that slight curve at the Motorola logo at the back makes calling a pleasurable experience as you can put your finger there. GPS locks just fine, in comparison with S4 it gets 1 or 2 less satellites outside, which is okay, accuracy is also slightly lower than S4, but almost on par.
Now the bad parts. First, and it's common, the camera. Honestly I always laugh at those persons who buy a mobile phone for camera, but still it's also true that you will carry your phone everywhere but you won't carry your camera. So for those who buy a device for mainly camera should wanna avoid this. I mean it's not terrible, but it's just not there. The problem is not with details, there are there, not at a good amount thought, but it's passable, the problem is with the inconsistency of it. You take a photo of red rose three times, and all three photos will come out differently! One might be underexposed, one highly overexposed and the other out of focus. The camera software also can't be any more worst to be honest. There is literally no option there. Minimalism is good, but not for camera interface, so that's a bad job by Google / Moto. I am using FV-5 now, it doesn't give you better photos, but the experience is better, as you can at least manually tweak the bloody exposure and WB, those are very basic stuffs!
But again, it will matter how you are using your photos. All my photos taken from my cell usually goes to Twitter or Facebook (for those ultra rare moments when I use those social crap) Instagram or Tapatalk, so for that purpose it's way more than enough. When the light is enough and if you can keep a steady hand with HDR then the photos should be enough for a 4x6" photo too, but when the light goes out, I mean at dark it's really bad. Way too many noise, way much loss of details! But again, if you take three or four shots then suddenly one shot will appear great, you will think it is coming from a different camera. So there it is, inconsistency is the main gripe about Moto X's camera. Other than that the camera is just fine.
Display, well coming from an S4 any display will look dull. But this one does not. It's a Samsung made OLED panel anyway, still. Unless you are highly obsessive about display quality and sharpness you are not gonna notice any bloody thing, other than the fact that this is a 0.4" shorter panel. The colours are punchy, the screen is slightly more over-saturated than Adapt display of S4, which might be good for somebody, but not for me. With S4 I always used the Cinema mode, so with the X everything looks a lot more over-saturated, if Moto could provide those Presets like Samsung I won't have any complaint, but they didn't. And as it's 720p the battery life is indeed better. Anything more than 1080p is an utter joke IMHO, just ridiculous, for 5-6" sized panels, a great selling point of G3 !
Storage space : Well out of the box I saw that 10.88 GB was available from my 16 GB model, which is pretty low IMHO. But well you can't do anything about that. You can always buy the 32 GB version if needed. Need to get one of those Dual OTG thing I guess. Someone please answer to my query about that in Mobile section.
By the way, the model which Flipkart sells is the Moto X XT1052 model, in case anyone wanna know. Which is an un-lockable bootloader model, so that's a huge plus. The bootloader unlocking process was smooth as butter.
And I knew I would hate this, but I think I am hating it more than I thought I would. SOFTKEYS. How on earth could some people like this is simply beyond. I can't think of a better idea to waste the screen real estate like this. Stupid. Anyway thanks to GMD Softkey app.
The speaker of this phone is beautiful by the way. I mean seriously they are as good as the M7 I used. I don't know, but this does sound like Stereo to me, without that Beats crap, even when it's actually Mono. But again, the speaker placement is not ideal. It should always be on the sides, like N95 or Nokia 1200
The Active Display. Nothing to say about that. One of the best way to notify you IMO, it's almost impossible to back to that blinking LED now. However I like the stripe type notification of some Sonys. About the Touchless Voice Control, haven't used it yet, don't think I would. Camera twist feature, nice.
So in short, after using this for just 48 hours I can definitely say I can never go back to TouchWiz now, it's just impossible. It's like getting a Honda City from my A4, sorry not possible. So for me coming from an S4 i9500 to Moto X was an update in every category other than Camera, and a tiny bit of Display resolution and maybe slight quality too, but I can any day choose a far better optimized phone than a phone which has a horrible and bogus Android skin making it slow and stutter like hell. As I said, this is not buying a gaming PC, specifications do not matter. Unless you are a super heavy gamer who plays games on mobile phones, or have the sharpest eye to notice difference beyond 330 PPI, or thinks that camera is everything in a phone, the Moto X is for you. This might be the only Android out there which just works (along with Nexus 5, but with it's cheapness), for those straight forward people who don't know about root, customisation etc.
PS : Just for an additional info, Sony's UI is good. I liked it. It's not heavy, some stock like feeling is there. And I saw that on my friend's cheap Xperia L or something.
