As much as I'd like to believe this usage of "sports" and "features" is just a journalistic bad habit that's hard to break, it seems much more likely to be sarcastic humor, given the PCWorld affiliation. We don't usually see those terms applied to negative traits. Imagine Ford advertising that it's new truck "features poor gas mileage" and "sports a brief warranty period". Yes, it's got to be sarcasm. Too bad it slipped into Macworld.
I'm all for banishing the overused terminology completely.

Last I looked, the technology of Lithium batteries does not like full discharge. This is very different from Nickel-based batteries where full discharge is recommended before recharging.
Lithium batteries are a little like a car battery in this sense, they should be kept charged, and discharged as little as possible. Running them to zero reduces their lifetime, sometimes considerably.
The above makes me wonder how does Apple know how many recharge cycles your computer has been through? I can guess, but does anyone know the answer?

I believe the base warranty is one year (90 days telephone support) and that AppleCare extends that to three years. I doubt the battery is warranted separately for 1000 cycles. Merely that Apple gives 1000 cycles as a base performance during that first year (or three).

So what is the point of this article?

System Profiler shows battery health and charge condition. There's also third party apps that make it easier to check that information for end users than opening up System Profiler all the time.

The point of this article, to me, seems to be to point out that user servicability is increasingly a thing of the past in Apple products. I think the benchmark might be the polycarbonite MacBooks, which had a user-replacable battery and even a hard drive that could be switched out in about a minute. The compactness of the new design comes at a price. If you're buying a new Mac and using AppleCare, this doesn't impact you much. But think ahead to five years from now, when used Macs will not be able to be kept running without expensive trips to the Apple Store. It's hard not to see this as Apple looking to keep as much service work to themselves as possible.

Look under About this Mac, Hardware, Power. This shows cycle count and health information. If you keep your MBP connected most of the time, your battery will not last as long as if you allow it to be exercised (run on batteries a couple times a week, then connect it to be recharged). Apple has a page that discusses proper battery usage, http://www.apple.com.../notebooks.html

That battery was rated at either 300 or 500 cycles. Only the built in batteries are rated at 1,000.

Nonetheless I must say I do not like the throwaway mentality. In this day and age, laptops do not age as fast as they used to. I have a 1st gen 2006 personal MBP for which I have changed the battery multiple time, that works very well. I plan to keep that one for as long as possible. I also use a work MBP from 2008 which I'm not thinking of changing anytime soon, for which I have upgraded the RAM and the HD. I've also upgraded my mum's MB HD and RAM.
It's OK to have a sealed MBA for instance, since the form factor is so tiny and they are not as expensive, the compromise might be OK, but I'm not so sure about at MBP. I think that in 4 years time 16GB will be too little and so will be the 256GB SSD.

Go to Apple menu -> About this Mac -> More info button -> Power
and there on the right you can find the cycle count.

My understanding of this situation is that when Apple introduced the non-replaceable MacBook Pro batteries they seriously upped the specifications. I don't recall exactly but I think the 2008-era batteries were good for about 250-300 full charge-discharge cycles, while the new ones are good for 1000. For heavy users of the older MBP models with easily replaceable external batteries a third replacement doesn't seem too bad. We won't know the actual facts about Apple's 1000 cycle claims for a year or two, but I suspect they wouldn't make such a claim without some kind of substantial lab testing results to back up their claims. It was the 1000 cycle claim that helped make the non-removeable-by-customer battery change totally acceptable to me as the new owner of a refurbished Feb 2011 MacBook Pro.
