Recharging mat for small devices

I was watching something kewl on the TV a few ago. They got this plate things out now that you lay your electronic doodads on and it recharges them without need to plug them in. I did a bit of digging and in 2006 CNet had a article about a similar deal that was called the WildCharger, this one a charger that could be rolled up. The WildCharge works by replacement of the back cover of the device with a compatible cover that has small nubs on it that allow doe proper contact with the charging pad.

I can't find the one that was on the TV, so will watch for the commercial again and do a bit of looking into it when I find it. I did find the Powermat PMM-HO100 Home & Office Mat (Black) at Amazon when I tried looking there. Not the one from TV, but same concept and got a 4 out of 5 stars review from reviewers.
