Redmond's situation is complex. Unlike Apple, it doesn't control the entire Windows ecosphere. It makes the software but not the hardware. Consumers typically obtain Windows via a third party--the the PC vendor, which works its toxic voodoo on the desktop. Furthermore, Microsoft and its OEM partners don't enjoy Apple's generous profit margins, and therefore must find creative ways to boost revenues.

If Microsoft truly wants a Mac-like experience for Windows 7 users, it should lock down the desktop. Non-commercial themes are OK, but tacky ads, movie promos, and other cheese ball garbage must go.

To paraphrase : Keep it classy, Microsoft.
