PlayBoy Magazine might not have had the HP TouchPad's price dead to rights, but it also might not have been far off the mark -- if this allegedly leaked Walmart database entry is correct, the 32GB version of the webOS slate will cost $599. PreCentral nabbed the above image, as well as supplementary documentation suggesting an $80 sticker price for the Touchstone Dock, $50 for a first-party case, $30 for a spare AC adapter and $70 for the official Bluetooth keyboard. Of course, that $599 price tag puts the 9.7-inch tablet squarely in the sights of Apple's 32GB iPad 2. We can't wait to see if it's worth the cash to pick up this underdog.
