And if webOS is basically web-based, that means that all of Palm's apps will be available on the iPhone, but none of the iPhone's apps will be available on the Palm Pre. Not exactly a winning proposition.
Well done for getting the design close to Apple's standards (though they had to poach a team of Apple people to do that, all the way down to the packaging that looks just like Apple's), but being a second fiddle won't win this war...
This is not to say that it won't be successful. This Pre is clearly a slick piece of kit. But it won't be anywhere as successful as the iPhone, and certainly won't do "better" than the iPhone.
