Apple's decision to use Intel chips could be bad news for Linux as companies looking to move from Windows may now be more likely to consider Mac OS X, according to an analyst.

It may "ultimately be a bad sign for Linux's fledgling move towards broader desktop adoption - especially among corporate PC users", said Burton Group analyst Gary Hein.

"Apple's operating system works very well and is known widely. It has the same power of Unix underneath, and it can run Microsoft Office natively," he told PC World.

He adds a number of other reasons why people may consider the move: "Some do in order to get more life out of old hardware. For others, it's a licensing, or it's based on anti-Microsoft emotions," Hein says.

But Hein is pessimistic. He notes that while many companies may think about migrating from Windows "no one's really moving".
