In fact, there are three points do consider:Unfortunatelly this is not true. I worked with several Windows developers that were starting projects on Linux, and they couldn't wait for the day they'll go back to Windows IDEs. Linux is a wonderfull platform for developers as long as they have that hacker-spirit, as we have :-).
Now, except for entreteirment applications, it is getting harder and harder to find MS "killer" applications... and I really think that that's all right not wasting money trying to bring pandora boxes like activex and the likes to linux. So wine is a good alternative.Microsoft's most killer apps are their IDEs and development frameworks. Because they know how strategic is to have the developers (killer and business apps) working for them.
