blueshockeynut, a forum user over at iPAQabilities.com was kind enough to post a number of pictures of the HP iPAQ hw6500 next to a number of other PDAs and phones, including the Siemens SX66, the Motorola MPx300, the Audiovox VOQ, the Treo 650 and an iPAQ 4150 with thumb keyboard.
Is it just me or does the mini-SD slot not look much smaller than the SD slot?
