My bandwidth is wider than yours
Imagine a radio technology that gives you 480 Mbps at short range. Imagine that you don't have to keep all those cables around to connect your gadgets. Make it low-power, too. You even want to be able to stream content from your super-duper cell phone to your way-too-many inches flat TV. Top it off, make it an open standard.
It's not just a dream: we have it and is called Ultra-Wide-Band, and it comes with many toppings of your choice (Wireless USB and WiNET; Bluetooth and 1394 following) to help remove almost every data cable that makes your day miserable. And Linux already supports it.
