How would you change the HTC One X

Flagship phones are tricky customers when it comes to How Would You Change. Often, they're handsets that have every feature thrown against the wall as companies see what sticks with customers. Hovering on the blistering edge of technology, it would seem there's very few things wrong with (staff favorite) the HTC One X -- although perhaps that makes any glaring that more notable. What we'd like you to do is place yourself in the position of HTC's design mavens and work out what omission they could or should address when it comes time for a sequel.
