While not committing to an actual commercial release, a spokesperson from HP's Personal Systems group did say that they're "in customer evaluations now and will make a determination soon on the next steps." According to the product summary on its website, the device includes an 8.9-inch touch screen, runs on Windows 7 Premium, accepts pen and touch input, and has two cameras -- video and still. Additionally, a separate listing posted by Energy Star says the Slate has a 1.6GHz processor and 1GB of memory.
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.
