After HP completed its Palm acquisition earlier this month, everyone pretty much assumed the company would drop its plans of a Windows 7 equipped tablet and focus on webOS instead. Well, that may not be the case after all. A listing for the HP Slate 500 appeared yesterday HP has said it wants to put webOS in tablets, and was recently granted a trademark for the term "PalmPad". It seems the company may ultimately release two devices, one running Windows and the other webOS. Given that the first is expected to have a full blown desktop OS and pen-input capabilities, some suggest it will be targeted at business users, while entertainment-focused consumers might be more interested in a platform that's actually built for mobile devices.
