Maybe not a secret, but not touted. A tech expert says that the most important feature of the new iPad may be something no one is talking about, Bluetooth 4.0. While the other features everyone is talking about, may be great, in the long run, the ability to use BT 4.0 in conjnction with other 4.0 devices (AppleTV) is going to make the new iPad extremely useful.
But the new Bluetooth can do so much more than connect a clunky earpiece. Bluetooth 4.0 isn't just a little better than the version currently built into most mobile devices. It's massively better.Bluetooth 4.0 has an extremely low-energy feature, which means supporting gadgets can run off wristwatch batteries, or hold charges for years, rather than weeks. For example, Bluetooth 4.0 enables wireless headsets that last weeks between charges. And it means that headsets can be a fraction of the size.
Wireless iPad keyboards don't have to be charged at all for the life of the iPad, thanks to Bluetooth 4.0.
Another magic trick Bluetooth 4.0 performs is that it allows pairing and data exchange without user involvement. If the user has granted permission in advance, two Bluetooth 4.0 devices can connect and sync data without even informing the user, just by being in range.
Bluetooth 4.0 also, ironically, even simplifies the connection of Wi-Fi devices. Right now, adding a Wi-Fi gadget often requires users to hand-enter configuration information. To oversimplify, Bluetooth 4.0 enables new Wi-Fi devices to get configuration information automatically; instead of asking the user, Bluetooth 4.0 enables devices to communicate configuration information with each other. The only user involvement required is permission.
