HP Jornada 565 here...it's great, and it's really an asset to my daily schedule planning. (I sound like an ad there, don't I
). I used to be absolutely sure of the superiority of PocketPC 2k to Palm OS, but after the release of the new Zire and the Tungstun C, I'm beginning the think that Palm's level of capability is quickly rising. The screen of the new Zire seriously looks like a picture. And of course, because PalmOS is already well designed and perfectly simple and responsive, having the XScale processor can really make the handheld device amazing to use. My next PDA (a year from now or so) will probably be the upcoming Dell Axim X3 or one of the color Zires. By then, I believe that manufacturers will have entirely ceased monochrome displays.
