Garbage phone. I started using my Galaxy S2 after a month with the One X, before I got the GNex.
Maybe if the One X had 2GB of RAM it would be better; but the combo of Sense and ICS, makes the One X so laggy that it is unusable.
The biggest complaint I have is how long it takes to download/update apps. If I go into the Play Store and there is more than 1 app to update, it will take forever. For example I had 7 apps to update the other night (I turn it on every now and then since my wife likes to play games on it) and it took literally 1 hour to complete the update. I have RoadRunner Lightning, which is speedy late at night, so there is no way it should have taken that long. The largest app was only 7MB as well.
