MacBook Air -- Standby Time

In fact, Apple is now providing a “standby time” for their laptops - it’s just the MacBook Air at this point, but it will undoubtedly spread to the rest of their offerings at some point in the future - similar to those doled out by cell phone manufacturers.

My almost 3 year old laptop will eat through 20% or so battery life while sleeping given about 8 hours. I say bring this to the other laptop models as quick as possible.
