What Palm is really doing isn't just spoofing the USB Mfg ID, but spoofing Apple on the whole. If Palm wants to compete, they should step up and try and release a well rounded product like Apple, and that includes the Desktop pieces. They have had many chances to do so, and blown almost all them. Instead they appear as pathetic with their feeble attempts to glom on to Apple. Palm leadership over the years is to blame.
Back in the day, Palm invented HotSync, and then promptly forgot about it. Anyone who ever tried to upgrade to a new Palm and suffered through all of the HotSync hassles that Apple now makes effortless, will be glad to simply see Palm go.
Apple pays attention to detail, and creates holistic environs that add huge amounts of value. They are not perfect in their openness or in every implementation (Calendar on the iPhone sucks, even compared to old versions of Datebook on the PalmOS, about twenty taps to create a new item, whereas Palm had that right by starting out right on the Calendar) but in general, Apple does a far, far better job with the whole enchilada. And if it doesn't sync well as a handheld, then it is useless.
People should simply spend their money on what is done well and allow the market to quickly flesh out losers. As a long time owner of dozens of handheld gadgets, and many Palms, Treos, etc. that's no contest, for now it's the iPhone. Palm is a loser.
