[AT&T, Rogers HTC One X, Telstra One XL] mobilehavoc:
I've had this phone for about 10 days now and I'm coming from a GSM Galaxy Nexus 4.0.4 which I still love and adore. Having said that I've decided I'm keeping this phone because like with everything while not perfect, the benefits to it outweigh the downsides. Here's my take:

Things I love about One X:

- Screen is spectacular and best I've ever seen yet. Puts Nexus to shame. Hard going back to Nexus after using the One X

- Camera - best camera I've ever used on any mobile device yet. Not just optics but the software is fantastic. Love the burst mode/best shot, HDR actually does something, panaroma, etc. Especially coming from Nexus, it's a HUGE improvement

- LTE - yes it eats battery like nothing else but god damn it's fast and it's glorious. My first cell phone didn't have data and the first one with data had GPRS (not even EDGE) so the fact I can be standing somewhere and get 25mbps down is just mind boggling. Love it.

- CPU - the S4 is a beast, I have a PS Vita and an iPad3 so I don't need my phone to be a gaming powerhouse but this thing flies. Noticeably faster for me in many apps than the Nexus and web browsing is desktop class. I can even leave Flash to always on and I don't even notice! Definitely future proof for at least another year.

- Build quality - superb and feels very solid. NO creaking and it's light but does not feel cheap. Galaxy Nexus feels great too but still feels cheaper and flimsy compared to One X. I have the white one and it looks very very nice.

- Bluetooth 4.0 - had some problems on stock ROM (related to wifi I think) but with 1.82 it's very stable and works great. Future proofing for newer devices coming now with 4.0. I'm a big Bluetooth user so nice having the latest spec.

Things I really don't like about the One X:

- Sense 4.0 - yes it's better than previous ones (I had an Incredible and a Sensation) but it's still a piece of crap. Unnecessary UI animations and changes just for the fact they want to change things. YES there are nice little tweaks they've done but those are for me the ones under the hood and not really UI ones. The memory management/multitasking thing is a great example of one gone wrong but for me personally, I LOVE stock ICS and I can't wait for an unlocked bootloader so I can run a stock AOKP ROM on it.

- WiFi - although the 1.82 RUU seems to have fixed it somewhat, it's still flaky. I have to have "best wifi performance" checked otherwise notifications don't always come through when phone is asleep.

- Battery life - I guess I can't be too hard on it because of the screen, CPU and LTE but it still is quite unpredictable. It's NOT BAD but it's not great for me yet either. I'm sure I'll get it to a point where it'll be reliable but right now it seems all over the place.

- Power button - why in god's name do the morons at HTC stick the power/sleep button on the top of the phone when every other manufacturer has realized it's more logical to put it on the side. Especially on a 4.7" phone!! Idiots. This is annoying but I can live with it.

- Wide phone - the screen is only .5 " bigger than the Nexus but the phone is much wider in my hand and not as comfortable but not a deal breaker for me.

- AT&T Crapware - can be disabled but irritating they loaded it up with so much garbage.

- NO Google Wallet support - I MISS THIS the most from Nexus. I have a Citi card setup and used it a ton daily but now I can't :(

There is probably more but these are the highlights. So yes, the phone is far from perfect but I'm not getting rid of my Nexus so I will still have that. This phone has what I'm looking for which is the camera, screen, network and cpu that beats my current phone...so I'll look past the other stuff that bothers me - at least until I can flash stock ICS on it.
