I have recently been introduced to Dell's wireless charging capability and now mobile phones are into it also. And actually, they are the ones who are most likely to adapt the technology first.
[Photo courtesy of Cellfanatic]The Powermat is a one-pad, one-plug system (pictured above right) that charges all your gadgets in one place without wires. Your gadget gets a special "Powermat Receiver" sleeve so that it can use magnetic induction charging to power your devices. (Aren't familiar with magnetic induction? If you've got an Oral-B rechargeable toothbrush, or a Palm Touchstone charger for your Pre, it's the same thing.)
What can be the weak point(s)? It can cost a lot
