I don't think I'm the same jdong you're referring to . As far as the whine, I think it is an age-dependent thing. I can hear it, but it isn't prohibitively irritating. I've also been told I'm really sensitive to high-pitched noises. I can hear the smoke alarm in my room taking 5-second samples. My head nearly exploded after working all summer on 640V hybrid auto powertrains that used 15kHz PWM switching. Of course, the classic example, as soon as I walk into the house I can hear my dad left the TV on upstairs in the bedroom.
Interestingly, for me the whine is also like a battery level indicator. The intensity and pitch of the whine appears to change as the battery reaches its last 30min or so of 100% level runtime.
Oh well. Oops.
I agree about the age. Seems to be almost 100% true.
