According to a USPTO document, HP has recently submitted a trademark application for the term “Palmpad”, a moniker that would be fitting for its first attempt at a webOS tablet. The application form lists the target goods/services as “Computers, computer hardware, computer software, computer peripherals, portable computers, handheld and mobile computers, PDAs, electronic notepads, mobile digital electronic devices”, a category of devices that describes a tablet to a tee. Another circulating rumor suggests that this “Palmpad” may ship with a capacitive touchscreen that supports digital pen input. A carryover from HP’s popular lineup of TabletPCs and Palm’s PalmPilot devices, this pen input would serve to set the webOS tablet apart from its primary competitor, the iPad. Anyone interested heightened by the possibility of inking or perhaps even graffiti on this rumored webOS tablet?
