It probably doesn’t. I don’t know.
My point is that it’s so darned convenient that going through the motions of saving everything and shutting down your Mac and the booting it up and launching all the applications every time you need it just to potentially make the battery last a couple more months is just plain… well, stupid, IMHO. If someone told you that your car would give you the best performance in terms of mileage if you drove it at around 40 KM/h, would you drive it at that speed all the time?
I bought my Mac about three years ago and haven’t given a second thought to what’s up with the battery and have not had to spend a dime on it yet. Even if it does go in the crapper one day (and I’ll have no way of knowing whether it did so prematurely, mind you), it will have been worth it for all the years of just shutting the lid when I’m done and popping it open and getting back to work in an instant.

Guys, I’m planning to buy a Drobo this January. It’s Rs. 25,000 without the hard drives. Should I go ahead?
