"There will probably be some pushback on that. There's already been pushback on buying Software Assurance because there's no guarantee [software] will be released during the term of the customer contract, " said David Orvis, license management services strategist at Software Spectrum, a Plano, Texas-based solution provider and major Microsoft reseller. "In some cases, it will help Microsoft get Software Assurance contracts. But Vista Enterprise being an entitlement only on SA? It will be a major issue. But I don't know how much of a backlash there will be."
Microsoft partners and industry analysts expect opposition to the requirement, since it is estimated that only 50 percent of Microsoft's business customers buy Software Assurance.
