In the end, the IDAPT I3 is a decent device and if it came loaded up with the iPod, Zune and NDS tips, I'd find it very useful.  The option to pick four of your favorite tips is a great way to get the IDAPT configured for your personal use.  Unfortunately, there is not Zune connector available and hopefully IDAPT will make the Zune one available in the near future.  It does save a lot of cable clutter and our own Fujitsu was sharing his own personal pet peeve of having an entire power bar dedicated to charging different devices. . .
