Acer: Windows 7 helped PC sales

He said the increase in sales was not so much because Windows 7 was a better operating system, but because of the natural cycle to replace or upgrade old hardware. Dell has also reported a slight lift to its own sales but hasn’t said if it expects more more sales.

Corporate buyers, which are Dell's biggest customers are still not too sure about Windows 7 and are waiting for a more mature product. They want to see how Windows 7 behaves on different hardware.
