Power button is too easy to hit inadvertently

When in ebook mode, the power button is on a corner that's likely to be hit by a stray thumb -- and it looks an awful lot like the rotate/backlight button, which is in a similar corner and is something you're likely to want to hit. Should this be changed in B3 hardware?

This can probably be worked around in software, by doing a slight dance when the button is hit. My suggestion: When power is on, the first press on the button causes host software to be notified, which puts up a notice. The notice says to press the power button again if you really want to power off the system. If nobody does that within 5 seconds, the notice goes away and you're back to normal.

Of course, if the system does not respond, the user can hold the button down for 4 seconds and get an immediate EC poweroff.

Alternatively, a short press on the power button could suspend the unit, rather than powering it off. This would make it less catastrophic to hit it accidentally; you'd just hit it again to power back on. But then how would you nicely ask the system to truly power ifself off?

The industrial design is closed at this date. At most, it *might* be possible to recess the button slightly.

Your suggestions on what to do if it is hit make sense, however.
