The “good” news about the PC market is that, by IDC’s count, it only declined by 1.7 percent in the last quarter. The only bright spots? Macs at the high-end and Chromebooks at the low-end. While Apple certainly wins when it comes to profit margins, Chromebook sales are surging upwards. ABI Research found that, in the most recent quarter, Chromebook shipments increased by 67 percent quarter over quarter. The research company expects that year over year, Chromebooks shipments will double.
