I just spent 20 minutes with the One X at my local AT&T store. My second round. Some observations.
The screen just blows away the iPhone 4/4S. It's honestly absurd how sharp it is. Whites are significantly white and everything just looks incredible. (Pictures, video, text, backgrounds, etc.)
Wi-fi was enabled however the sales rep told me they were having an issue with the cellular connection (I didn't ask what exactly). The rep was nice enough to download Chrome Beta for me to mess with.
Chrome Beta over wi-fi was faster than Safari on my iP4. I was able to handle the unit somewhat easily with one hand. I have smallish hands but was able to reach the address bar with my thumb in portrait without too much discomfort. I think the light weight of the device and curved backing help a great deal with respect to using it with one hand.
There were seven levels with respect to increasing and decreasing the volume. I believe the iPhone has 16 levels.
The unit I was handed appeared to have full power. Because ICS does not have a battery percentage indicator by default, I was unable to notice how much battery I lost in my 20 minutes on wi-fi. When I returned the device it did not appear as if the battery icon changed much, or at all.
I do have one serious gripe, and it has to do with Chrome. In order to access your bookmarks, you need to tap 'Menu' and then 'Bookmarks'. On Safari I simply tap the dedicated bookmarks icon. So it's an additional step, and while it may not seem like a big deal, it most certainly is. At least for me it is. That extra tap is a pain in the arse. I spend a lot of time browsing on Safari with my iPhone and I can't get used to that additional step. I can't believe Chrome doesn't have a dedicated bookmark icon like Safari.
The stock browser also has no bookmarks icon. You need to tap 'Menu' then 'Bookmarks' just like Chrome. Puzzling.
Also the Chrome browser does not have a '.com' button on the keyboard. The stock browser on the One X (and Safari of course) do.
Out of curiosity, does anyone know of any Android browser that does have a bookmark icon? Dolphin perhaps? Opera? Perhaps Chrome will adopt this feature down the road.
Anyways, that serious gripe aside, I didn't walk away making a decision. I was banking on using Chrome if I jump ship, but this bookmarks issue really bothers me. I think I'm still going to wait till after WWDC to make a decision.
