Oh wow, that looks great. I wonder why they cancelled it? It also reminds me of the Casio ClassPad 300.
Good observation.
That's because the ClassPad is actually based off this. Uses the same processor, stylus input, etc. In fact, the company that developed the software for the Xpander, Saltire, is the same company that developed the CAS for the Casio ClassPad, because when HP canceled the Xpander project, Casio immediately contracted Saltire. To make it easy to port the software from Xpander to the ClassPad, a lot of the hardware had to stay the same. IIRC, it was HP Australian R&D who developed the XPander hardware. However, they were laid off and the engineers went on to create another company and started on another project, called Project Qonos. However, they couldn't get enough pre-orders to start production so it never came to market. Hopefully, that won't happen with Project Paradise.
