The PC industry is keenly awaiting the launch of Windows 7 in the hope that it will deliver it from its woes. Probably, Apple also has its sights firmly fixed on the sandglass counting down to the launch, but for a different reason, of course. Apple need not be fazed by the launch, though, if Broadpoint AmTech analyst Brian Marshall is to be believed.

According to his analysis of previous Windows releases, a Windows launch has no negative bearing on the sale of Macs. In fact, previous Windows releases have acted as a catalyst for Mac sales.

“We have concluded that no negative correlation exists on Apple’s (AAPL) hardware sales when Microsoft launches a new OS. Ironically, we believe new OS launches from MSFT may have even acted as a ‘delayed accelerant’ to AAPL’s computing sales,” Marshall wrote in a report.
