Yes, I'm aware that my "weekend" expectation is...mmm...a bit unrealistic :-)
My point is that it's just unbelievable to me that something so glaringly wrong escaped testing.
I do not think your "weekend" expectation is unrealistic at all. The SP4, for example, (and probably the SB) has a warning on the box: "Battery has limited recharge cycles and may eventually need to be replaced by an authorizes service provider." All the power issuea -- likely software-caused -- thus reduce the hardware life of this product." I would hope that that an issue that impacts the hardware so significantly would cause Microsoft to work overtime on this issue.
