I'm a bit more concerned that their isn't a dedicated power button. My Mac has froze a dozen times in the last year, and I'm pretty sure a soft button isn't going to be working.
*Well, actually I'm buying another ThinkPad.
Its a touch button, so not necessarily "soft", but even if the console is completely locked, holding your finger on it for about 5-10 seconds will reboot. I'm sure they can do something similar (the far right side, if held down, will always be power, etc... and it can work as a touch power button only when the machine is asleep/off)
