I'm using a D-Link BT dongle (DBT-120) on my Cube in my home theater. It works extremely well. I just plugged it into a USB hub that I have connected to the cube and it worked instantly. I'm not using the dongle for a wireless keyboard/mouse solution. I'm using a Logitech wireless keyboard. My Cube is the main driver for my 30,000 + MP3 collection. I have a 250gig external firewire drive with all the tunes on it. The Cube is integrated into the theater through my Denon 5700 AV amp and my Mitsu 50" TV. The theater set up is available throughout the house. This is where BT comes into play...via Salling Clicker. I use the bluetooth adapter in order to use Salling Clicker ( http://homepage.mac.com/jonassalling/Shareware/Clicker/) and my Nokia 6600 to control my tunes throughout the house. Salling clicker is an excellent bargain at $19.95. In addition, I bought iDisco ( http://www.snarb.tk/). It's a better iTunes controller than the one that comes with Clicker. Another BT app that I have on the Cube is BlueToothElite ( http://www.reelintelligence.com/BluePhoneElite/). It's a beta app but works great. For one thing, it pops up callerID info on my TV whenever my cell phone rings. This is nice if I have the Picture-in-Picture on my TV set with the Cube in a window. It also has nice proximity features like automatically starting the screensaver, pausing iTunes, changing my iChat status, etc. when I leave the range of the dongle. Those last features I use in conjunction with the BlueToothElite app on my Powerbook when I'm at work. Anyway...the D-Link dongle works quite well with my Cube. Man I love my CUBE!
