Doubts are hurled on Microsoft's decision to feature comedian Jerry Seinfield on its $300-million "Windows, not Walls" campaign airing on Sept 4. Experts say Seinfield's presence won't lure college-age and younger crowd and convince them not to switch to a Mac or to switch back. However, he may have greater influence on the thirty- and fortysomething business community.Some think Seinfield's lack of recent hits won't grab any more Microsoft customers. One thing that's commonly argued is Seinfield's scope of influence on the young. Most people believe advertising should focus on the younger generation as today's technology is frequently used by the younger crowd.
