Combo is a poor term. It makes me think 1 end, 2 uses and the geometry just doesnt work- unlike combination a XLR and a 1/4" jack

. I think that they/you mean a cable that terminates in two separate ends. I have some issues, what kind of terminations at the end, A,B,m,f, mini, normal, side by side, or separate. Luckily, they are all so different. No mistakes as to how to plug it in. I agree with Macwhispers commentary. The cable makes little sense and I couldnt figure out how it would fit into Apple's product lines. Perhaps a dongle for a new portable product?
The rumor also never states that Apple ordered the cables, just that an OEM that produces products for Apple is creating a product. There is to little information to make the report useful. I just need more before I get excited or wishful.
If it does pan out, Macwhispers will again have the best scoop on secret information.
My wireless mouse sucks down batteries, but my keyboard doesnt. Wireless is cool, but not a necessity.
