"The core specs you need to know are these: It's a quad-band phone, which makes it usable on any GSM network in the world, and has GPRS for internet access. The processor is a 312MHz Intel PXA chip, descended from the popular ARM family, and twice as fast as the 600. (You can feel the difference, too - the 600 wasn't slow, but this is pretty nippy.) The touchscreen has also been upgraded to 320x320 pixels with 65,000 colours, bringing it in line with most of palmOne's other devices. Full Bluetooth capability has finally been added alongside the existing I/O options of infra-red, the SDIO slot and the sync-port. The camera, while staying at the same VGA (640x480) resolution, now produces much better images than the 600's frankly dire CCD, and the new software also lets you take short movies."
