Excellent news, although I expect we'll see in the coming months that Tim Cook will take over as CEO and Jobs will probably become chairman or something along the lines of being involved in development and strategy of new products. A reduced role for him makes sense seeing as the company did very well without him the last six months.
Steve's next, and last, keynote will be to debut the mythical tablet.
I also suspect he'll pass the reins to Cook by year's end.
