#2Interesting experiment, but watch out for the vertical scale on the charts showing capacity against time.

#3Wow, this is an excellent article! Nice visualization of the battery life.
I am quite nervous about the battery sealed inside my own new Macbook. Is it better to attempt to use the battery as much as possible in order to get a new one before the 3 year Applecare Warranty expires? Or to maniacally keep the machine plugged in if at all possible? Or simply not to care? The price of a replacement will be high, and I wonder how many years it will even be possible to replace these batteries.
The thinness of my laptop is amazing, but I would rather have a battery that is not GLUED inside the machine.

#4If your cycle count is 223 and you are nearing 80%, then your battery is defective, plain and simple. Apple will replace it. It's happened to me a couple times and Apple took care of it with no hassles.

Yeah, not pegging the axes at zero makes for a much more dramatic graph -- a classic way to lie with data viz. Sometimes it's fine to do that (e.g. because without scaling it's impossible to visually understand some of the data), but the context should be made clear.
That said, the plot of the Macbook Air's battery performance vs. the Macbook Pro's is really interesting. I haven't done the tracking, but this agrees with my anecdotal sense is that my 2011 MBP (likewise a main work+personal system) has had really excellent battery longevity relative to prior Mac/other laptops I've used.

#6My 2011 MacBook Pro is doing a lot better than my 2007 one. With similar use, the older MacBook went through about a battery every year and a half, replacing once they could only hold up an hour or so of charge. I'm up to 750 cycles and holding high at 98% "health".
The OPs MacBook air sounds defective, or at least, under-performing.

#7>letting the battery cycle*
Wait- I thought that was for NiCd batteries and Li-ion batteries where suppose to always be topped off? Furthermore going below 15-20% charge hurts their max charge level?
*By cycle he means running it down and charging it up?

Its really NBD. My 2010 MBA still holds a solid 5-6 hours, down from maybe 7.

#9anyone know how to do something similar on a windows laptop?

Yeah, can someone who knows how this shit works chime in? There's a lot of conjecture on the internet but few answers. Apple's advice seems to be "don't worry, be happy, don't let it be in a discharged state for a very long period of time, occasionally cycle through it".
I'm on my third battery for this 2009 Macbook unibody (granted, the first one was water damaged but still…), and 300 cycles in it's starting to give me Service Battery warnings and I must be doing something wrong.
