No surprise here that antitrust concerns with Microsoft are far from over, and that several companies are expressing such concerns over Vista, the next version of the Windows operating system.

The U.S. Department of Justice and state attorneys general are gathering information on the complaints and have not decided if they have merit, according to a report filed Wednesday with the judge overseeing Microsoft's U.S. antitrust compliance.
Several objections to Vista have been raised, such as concerns that Microsoft will use its control of Windows to push consumers to use other Microsoft products, such as its browser and media player. Vista, which is already likely to be delayed, could be delayed further if these objections stick.
