Jobs back at work, Apple confirms

Apple has confirmed that CEO Steve Jobs is back at work following six months of medical leave.

But the 54-year-old Jobs, who recently undertook a liver transplant as treatment for his prostate cancer, will work from home a couple of days a week.

Apple stock on the Nasdaq fell slightly to $141.95. By contrast, news of Jobs' medical leave alone caused Apple stock to fall.

Analysts told Reuters that investors had become used to the idea of a Jobs-less Apple.

Some speculated that COO Tim Cook - who served as interim CEO during Jobs' medical leave - may take over full time, leaving Jobs to take an advisory role.

The Tennessee hospital that performed the liver transplant said Jobs had an “excellent” prognosis.
