"The PPC-6601 is a Windows Mobile Pocket PC Phone running the Windows Mobile 2003 Pocket PC Phone Edition. As such, it’s quite a bit larger than the svelte smart phones that Sprint sells. The PPC-6601 comes with a Lithium-Ion battery, DC converter, AC adapter, a dual-slot USB Sync cradle (so you can charge the device and a spare battery pack simultaneously), a carrying case with belt clip, a stereo headset with Microphone, 2 styli, an installation guide and an installation CD. I have to admit I was glad to see the sync cradle is included since there seems to be a trend of using cheaper sync cables instead. The carrying case works well, holding the PPC-6601 sideways in a "holster" with a magnetic coupling on top. The phone could fall out if jostled, but during my tests I had no issues with the carrying case."
When I read this review and the constant mentioning of the Treo 650, I couldn't help but think of good ol' Walt Mossberg, Hater of All Things Microsoft. The Treo is a big player in this arena though, so the comparisons are natural (if a bit unfair in some places).
