I was trying out the Hero this afternoon, and I noticed that the 'back' button is a bit awkward placed. It felt like it was hard to reach with my thumb when holding the phone in one hand (the rightside hand). The Magic has the back button closer to the trackball, which is much easier to access. Anyone else have the same experience? Or am I the only one that uses this button quite often? Is there a possibility to re-map the hardware buttons?
