Gartner tonight followed up on IDC results by supporting views that Apple has closed on Acer in the US computer market. Apple in its view jumped to 10.4 percent share with 1.83 million Macs; the figure put it less than 17,000 computers away from Acer, whose share plummeted to 10.5 percent. The analyst group wasn't as optimistic about Apple's performance as it only would have shipped 13.7 percent more computers, although this was well over the 2.2 percent average.
