IBM is rumored to have put its PC business up for sale, reports People “close to the negotiations” say that IBM is in serious discussions with Lenovo (formerly known as Legend), China’s largest maker of personal computers, and at least one other potential buyer for the unit. The sale, which reportedly will be in the $1 billion to $2 billion range, will include desktop, laptop, and notebook computers manufactured by IBM. It is unclear how this will affect IBM’s computer chip business, which currently supplies Apple with its PowerPC G5 processor. [Thanks to MacMinute reader Marc Pope for this news tip.]
