This is how the battery on my 8 year old Windows laptop is doing:

4 minutes is an overestimation, I expect no more than 2 minutes until it dies. It's still very useful when the cable is accidentally pulled out or when I want to change power outlet.
About the MacBooks, does the battery usually get that bad? I have a 5 year old iPad 2 that I have used for about 5 hours almost every day (it's my main computer) and I still get about 8 hours of battery life. I thought newer batteries didn't usually degrade to less than 60-70% of the original capacity.
I had a 3 year old MacBook Pro that gave me about 3 hours (out of the factory 8 hours) battery life at half dim brightness and idle. Almost 2 hours at full brightness. I'm just ready for a new battery tech to come out that replaces Lithium.
