The sales of office Mac at half-mast

According to NPD, November was marked by a significant deceleration of the sales of the office Mac that have fallen by 38% whereas portables increased by 22%.
Concerning Windows, the fall of the office machines of office was definitely lower with a fall of 15% while the market of the portables gained 7%.
One can suppose in addition to the economic crisis, many potential buyers the iMac and of the Mac Pro await an update of this range while the sales of mini Mac, having now a calamitous ratio of innovation/price were completely stagnant.
All that remains is to hope that these poor figures push Apple to renew its "desktop" range as fast as possible.
