"In addition to IDC's downward revision, Intel also downgraded its sales outlook for the first quarter overnight. That's why local PC makers and vendors came under some pressure this morning", said IDC.

Intel at an investor conference said its first quarter revenue will be US$12.8 billion, plus or minus US$300 million, a drop from an earlier target range of US$13.2 billion to US$14.2 billion. The drop reflected the general weakness in the PC business worldwide.
