Is there any chance that Handoff won't require Bluetooth at all, in the wake of everyone posting about Bluetooth LE being a requirement? On Apple's website, NONE of the pictures showing Handoff have the Bluetooth icon in the top right corner of the devices. Also, when Handoff was demoed during the WWDC keynote, the iPhone and iPad used also did NOT have Bluetooth enabled. I realize this could just be a huge oversight on Apple's part, but they are normally good at not making mistakes like this. Thoughts?
