I am late to the party but have two Skydocks (one for me and one for the wife) and have enjoyed them so far. I use the Tom Tom app with traffic on my phone so it is helpful to have everything being run through it.
Bluetooth wise I haven't had issues where my phone connects to it but the Skydock plays through the stereo with ease. Love the ability to mute the music when a call comes through.
Only complaint I have and it is minor is when multitasking, the app has to load up again so it takes a few seconds for favorites and song data to come up.
