XtremeMac has taken the wraps off an interesting little $80 accessory called the InCharge Home BT that adds Bluetooth streaming capabilities to any speaker or audio device with a line input.
As you can see from the image, it also acts a USB charger and comes with USB to 30-pin connector for iOS devices (it won't charge the iPad, however) and a 3.5mm jack cable. What you can't see from the picture is that the unit plugs into the wall.
If you're looking for something like this for your car, fear not, there's also the InCharge Auto BT ($80), which allows for wireless audio streaming to your car stereo, hands-free calling, and USB charging.
Both accessories appear on XtremeMac's Web site but aren't for sale quite yet (we wish they cost more like $50-$60). They're also a bit of challenge to locate on the site, which could double as a hidden-objects game.
