What are the things that annoy you most about Bluetooth? If you answered "poor battery life, and pairing," then Broadcom has some good news. It is already making a chip that will allows keyboards to last for ten years on a single pair of AA batteries, and doesn't even require pairing.
The Bluetooth 3.0 BCM20730 chip is available as a reference design to anyone who want to try it out, and uses various firmware tricks to "dramatically increase battery life" and lower power consumption to match that of Bluetooth Low Energy (LE) products.
The big difference is that Broadcom's chip is also backwards-compatible with any older Bluetooth peripherals, so you would be able to use a BCM20730-containing keyboard with your old PC.
Pairing, too, will be eliminated by using USB HID Emulation, letting peripherals connect automatically to computers.
Broadcom had me at "ten-hour battery life." Seeing as I usually only pair any device once in its life, the fancy USB HID part isn't a big deal. But never having to charge anything, ever? Count me in.
