I may be in the minority, but I've never been a fan of docks. When you want to search or change songs, it's a pain having to walk over to the device. Plus the strain it puts on the connectors when you are pressing on the screen when drunk, can't be good. Definitely wifi, with a 1/8" jack for backup.
