Global PC shipments fell 13.9% Y/Y in Q1 to 76.9M units, per IDC. That surpasses Q4's 6.4% drop and Q3's 8.6% decline, and is steep even in light of IDC's recent commentary. IDC: "It seems clear that the Windows 8 (MSFT) launch not only didn’t provide a positive boost to the PC market, but appears to have slowed the market." H-P (HPQ) was the market's leader, but its share fell 200 bps Y/Y to 15.7%. #2 Lenovo (LNVGY.PK) saw its share rise 210 bps to 15.3%, and #3 Dell's rose 40 bps to 11.8%. Apple's (AAPL) U.S. share rose 60 bps to 10%, though U.S. Mac shipments fell 7.5% to 1.4M.
