In case anyone does not realise:
(I know some who didn't)
You can use the left and right "bumpers" to go change sections left/right... you don't need to scroll all the way to the top and then go left/right.

Cloud saving:
Gold only. 512MB storage.
With Cloud saves enabled, each time you load a game you'll be asked which storage device you want to use, e.g. HDD or Cloud.
Also, you can copy existing saves to the Cloud, and use it as a backup (so long as the save is copyable), or you can move existing saves to it and use the Cloud as the main storage for that game.
Within the system files section of local Storage, is a 512MB cache file. All Cloud saves are actually saved here initially, and are then uploaded to the Cloud storage when you shut down the console (with any files on the Cloud which are newer than local downloaded)... It's all kept in sync. So don't worry if you think it's not turned off when you shut it down, it's just using the background download feature to sync the Cloud storage.
Apps:
(e.g. Sky, Zune, Last.fm etc.)
You will need to reinstall these once you have the new Dashboard... possibly also delete the old ones first.
