    There are not many consumer devices that requires long battery life OVER data transmission speed. Limited usage for things like heart rate monitors.

    It is listed as Bluetooth 3.1 on the official Bluetooth website --- but there is no such thing as Bluetooth 3.1.

    You click the "technical information" and then click further on "view PICS details" --- the Playbook passes Bluetooth's original core 4.0 specs (but not the amended Dec 2011 4.0 version).

    It's a good excuse to stop over in Asia for a day of light shopping as well. Akihabara, anyone?

    A complete disassembly of the new iPad has offered a glimpse inside the hardware, including a Samsung-built Retina display and A5X processor.



    Yeah, not really news for anyone who follows AI regularly...

    Apple could just use a 1.2 GHz A5 in the next iPhone, if they want to increase CPU/GPU performance at all. They'll need the MDM9615 if they don't want to have thicker device or a bigger device.

    3) So that leaves about 40% more power draw to the display assembly?



    My guess is that out of the ~4.7 W power draw with LTE web browsing or video streaming, it'll be about:



    MDM9600: 0.5 W

    A5X + RAM: 0.75 W

    Display: 3.5 W (50 to 70% brightness)



    Everything else is assumed negligible. So, if they want to make any headway into reducing power consumption, they need that IGZO display tech in addition to finding more efficient LEDs which power the backlight.

    Yes, I agree --- with a process shrink, Apple can jut put a faster A5 on the next iphone.

    If the frequency is the same and the voltages are the same, this power consumption is just linear with the increase in number of transistors. The extra two GPU cores was about 30-40% of the die space in the A5 die pictures. So ~30% if it is using the same fab process as the A5.



    Wait and see.



    Hoo boy. If the A5X is really a 45nm part I will be returning my pre-ordered 16 GB Wi-Fi. The battery in the new iPad may be higher capacity, but it'll take longer to charge and a bigger/hotter SoC will cause its capacity to decrease more rapidly.

    Broadcom BCM4330 802.11a/b/g/n MAC/Baseband/Radio with Integrated Bluetooth 4.0+HS and FM Transceiver



    SWEET, this thing has an FM Transceiver! NOW i can't wait until tomorrow!

    The chip may have a FM tuner, but does it have a FM antenna attached to it.

    Well if it's like most devices it just uses the wire off of your earphones as the antenna. At least that is what my phones do.

    So you are telling me that you won't get FM radio if you just use the ipad's internal speakers?

    really makes me wonder what the point of all the lawsuits are....... odd.



    In the last year or two, a Samsung exec flew to California and met with Apple (maybe Steve) and Apple locked them into a parts deal that runs until about 2014. Sammy can't run away from that contract without suffering serious losses in revenue as well as legal judgments for breach of contract.



    Apple commenced the lawsuits right after inking that deal. They knew what was coming, but I don't think Sammy did. I think Apple's working hard to develop other supplier relationships before 2014, when Sammy could (but probably won't) cut ties with them.

    There are some health devices which already use bluetooth 4.0.



    Nike Fuel band is bluetooth 4.0. I think that we're going to see a lot of 4.0 accessories this year.



    Not sure why, but my 4S does not detect my MBA when both have BT enabled. It just doesn't work seamlessly, IMO.

    That's the way the iPod nano 4th gen did it. Very handy thing to have.

    What about BT headsets? Or wearable computing devices like Nike Fuel Band and it's successors that can monitor many vitals and then trickle update data periodically or remote controls that don't require line-of-sight?

    The ipad 2 , iphone 4s and iphone 4 all have fm transceivers in them also. The ipad 3 will not be any different. Apple will not have it enabled.

    I don't know whether BT 4.0 is fast enough for streaming audio because its throughput is about 200 kbps.

    Cost is probably a big issue.



    Another issue is performance. In this regard they most likely needed a significant increase in bandwidth over the A5 to push all of those pixels.



    As to process technology it would be a disappoinmet if they didn't make 32nm but I suspect they where heavily focused on other engineering issues to deliver this iPad. It also makes me think iPhone 5 will have an entirely different processor.



    Hopefully somebody will take it upon themselves to pull one of the A5X chips apart for an under the skirt photo.

    I wasn't thinking about when it's on a call, I was thinking about it being in BLE between calls for an enhanced standby time (speculative). BLE also allows for a faster setup time, too so when you press and hold the button to talk to Siri or a local phone system to make a call it may appear more responsive.

    The new iPad boasts obvious improvements such as a sharp Retina display, faster graphics, and 4G LTE but it breaks Bluetooth ground, too, which is just as significant.

    Oh neato, two devices (that probably aren't in production yet) to use BT4.0! Until there is some decent adoption of this protocol, no one cares about it. Just like thunderbolt. Speaking of thunderbolt, can't wait to get my USB 3.0 docking station.

    That meeting was with Tim Cook after he became CEO in late last year, they decided to extend the deal to 2014 and among other things increase SSD's in the MBAs. Samsung has no reason to "run away" from the contracts. Why would it relinquish the prestige of having its arch-rival depend on it for critical components.
