Since when has a laptop (or computer of any type) *needed* 30 years of power?If it was cheap, I'm sure people would find ways to use those batteries
but since you have to pay for the energy one way or another, I'd really prefer a 5-year-battery.
If it happens once, it's a bug. If it happens twice, it's a feature. If it happens more than twice, it's a design philosophy.
