The CNET reviewer is a big fan of the Portable Media Center (PMC) and raves how intuitive it is. He is though not pleased with the button interface of the Gigabeat S. The 2.4 inch screen also lacks the vividness of the one featured in the Creative Zen Vision:M for instance.

If the portable media players by Microsoft partners such as Toshiba are not gaining on Apple's market share, Microsoft might really have to launch their rumored portable gaming and media gadget to fight Apple directly.
