The CEO also mentioned that the current trend shows no sign of slowing:
"On the server side Linux continues to grow nicely, a bit faster than Windows. We're seeing a move to Linux in critical applications, and Linux migration has not slowed down."
Most interestingly, he spoke on the issue of patent infringement. Despite of Dell being one of Microsoft's largest customers, it seems that Microsoft has not shed any light or offered any information on the supposed "patent infringement" that Redmond has been looming over the heads of everyone around the world.
It wasn't all cheery news for Linux though, with Dellís Chief Marketing Officer mentioning that its growth is relegated only to servers and that desktop growth was minimal. Still, it's encouraging news.
