Battery life expectancies
I've read many reviews of laptops and quite a few mention battery life in terms of the number of hours use on a full charge.
I've not seen any comparison of the life of the battery in terms of how long it lasts before you have to replace it, as opposed to recharging. I know that this is not a simple 'test one machine and get a representative answer', but it would be a useful industry standard. Maybe you have enough readers who would contribute data that some conclusions could be drawn.
My own experience consists of three laptops. All used for a similar mix of applications, all went through a careful charge cycle before first use, and all used predominantly attached to the mains. My results were one Compaq Evo that was still giving three hours useful service when the machine was stolen at four years old and two Dell Inspirons that both had hardly enough life to boot the machine with the battery at just over 6 months old.
Not a statistically valid sample, but enough to suggest that there may be a brand dependent cost of ownership issue with the battery life.
