We just received a new MBP 15" to set up here at work, and I noticed that the front edge (basically the palm rest edge) isn't sharp anymore. In fact, it's been rounded all the way around, just enough to make it more comfortable without damaging the look of the machine. Way to go Apple for listening to us! This change could be several months old; we haven't ordered a new machine in a while. But this is the first one I notice with the change.
