This is one hell of a Auction and everything is either designed buy Jony Ives and Marc Newson, or its something they both would love to own and or tweaked by themselves.
Watch the 4min video (i just love Bono's Passion) and enjoy some of the things that will be in the auction, as well as a link to them as well.

Apple's Jony Ive discusses design in new video ahead of Sotheby's charity auction - Macworld Australia - Macworld Australia

In total, there are 44 items in the auction. Many are items that Ive and Newson simply really love, some that they love but that they couldn’t resist tweaking, and some that they’ve built from the ground up. The latter includes a Desk designed by Ive and Newson that is among the items with the highest selling estimate, at $320,700 – $534,500.
PS :Just for the Kiddies, Bono uses a swear word right at the end, but in the way he uses it, it is such a powerful way of doing so, and i love the way he does use it, and what he describes. . . . No Spoilers
