No iPod Out On Lightning Connector

Apple's new standard connector may or may not come with an old style dock connector adapter included in the package (currently Apple says not) but even if it does it won't support iPod out functions of the dock.

Not a huge problem, unless you're connecting to an accessory that requires iPod dock compatibility - most cars which take track info for displays for example - but worth knowing before shelling out your hard earned on Apple's proposterously priced adapter.

You might also want to consider the load bearing properties of the adapter before plugging it into any devices which physically support your iPhone...
