HP's been extremely direct in saying that it plans to release webOS tablets and other devices in the future, and now that the Palm acquisition is complete, it looks like those plans are starting to move forward -- the company just filed a trademark application for "PalmPad," which certainly sounds like a webOS tablet to us. We don't know much apart from that, but it's certainly an encouraging sign -- and we can't help but feel a twinge of nostalgia for a name that harkens back to the glory days of the PalmPilot. Now we're just wondering when (this fall?), how much, and -- as usual -- what this means for the HP Slate. We'll keep our eyes open.
