Longer lasting Bluetooth Headphones are all I want
Isn't the problem with headphone battery live rather the actual power consumption of the amplifier / speakers over the bluetooth receiver?

Why would it need your permission?
Why would it not need my permission? I don't want advertising just randomly being sent to my BT 4.0 devices simply because I'm nearby, any more than I currently want other people's BT 2.0 devices to pair with mine without my permission. I'm walking along and my watch receives an ad for the porn shop across the road? No thanks.
AirPort requires joining (unless you set your device to be promiscuous, for which you takes your chances), which implicitly means I'm giving permission. And I'm not talking about permission from the base-station end, I'm talking permission from my end. For my computer to be touched by another network or device. Because while the focus is often on the networks and services being offered, end-points are also subject to the two-way-street of permission granting.
Bluetooth always on in your pants. Testicular cancer (And the female crotch cancers too) here we come

Though I see this as Apple peripherals lasting longer on a single charge of the rechargeable batteries before you need to recharge. So less charge cycles for the batteries in a set time period is always nice.
Just my 2 cents... But BlueTooth 4.0 in the MBA is a bad sign for anyone hoping for an NFC-enabled iPhone 5.
After all, BT 4.0 is comparable in some ways to NFC: low power sipping (versus virtually no power consumption for NFC...), portability... But in addition to that it can stream data.
Except maybe no one else than Apple will be using it.
I've logged about 14,000 miles using the Nike+ kit ever since it was introduced about 5 years ago. And I've burned through at least a dozen of the Nike+ sensors. Never did I have one whose battery lasted a full year.
Just sayin'...
So.. the BCM20702 gives Bluetooth 4.0.. while the BCM2070 in the MBPs earlier in the year gave Bluetooth 3.0? I feel a bit cheated
Also there's the whole thing about Apple saying it only has 2.1+EDR.. confusing..
still you can not send/share music over bluetooth!
Actually i believe that NFC uses more power than BT 4 low at least that what I have read.
Well you could, but the Labels would never allow this...
Too bad Bluetooth 4.0's swiss cheese-like security is only marginally improved from earlier versions of the standard.

How about instead of that pie in the sky crap we get mouses with extended battery life.
1) Airdrop (Mac-to-Mac file exchange)
2) iOS 5 Wifi syncing
why bother with Bluetooth then...
Just a quick calculation on that shows you to be a dedicated runner...
14000 miles in 5 years is roughly 7.5 miles/day every day since then. Wow!! Impressive stuff
Proximity - wireless locking and unlocking
I think I would start wearing a watch if it would unlock my iPhone when nearby. I need the passcode in case someone steals my phone, but I get a little sick having to enter the code all the time.
Both of those requires an AP in infrastructure mode. BT doesn't.
