Table: New Questions about Microsoft

With its landmark antitrust case set for another round of hearings, some rivals fear the proposed Justice Dept. settlement won't constrain the software giant

PALM (PALM ) contends it has been denied technical information needed to develop software and make its devices function smoothly with Windows. That could give an edge to handhelds using Microsoft's software.

SONY (SNE ) argues that Microsoft (MSFT ) is using its settlement with the Justice Dept. as leverage against PC makers, forcing them to accept unfavorable licensing deals.

SBC (SBC ) charges that Microsoft will leverage its operating-system monopoly to dominate phone service on the Net.
