This year's most prominent tech trade shows were as notable for who wasn't in attendance as for what was unveiled.
Despite tons of rumors circulating about what we could expect to hear from Apple this week at Macworld, one announcement caught everyone off-guard. After insisting for months that CEO Steve Jobs' health was a private matter, Apple changed its tack in the face of widespread speculation that Jobs' weight loss had contributed to his decision to skip the conference.
On Monday, the company issued a statement that Jobs was suffering from a hormone imbalance that was "robbing" proteins from his body. That news cheered Apple investors, who dreaded far worse news regarding Jobs' health after a report last week that his health was "declining rapidly."
