I want a device to place on my bedroom dresser at night to dock my Droid 4, recharge it, and display an alarm clock. I plan to run the Droid 4 in Airplane mode to prevent cell phone calls, text messages, and any other network traffic. I don't plan to listen to music in this setup: always-vissable alarm clock mode only. Does anyone have experience with the HD Dock? Is that what I want?
