Microsoft published a new website, Origamiproject.com, hinting a new product will be released on the second of March 2006. Details are scarce but it appears to be a small Tablet PC style device.
We don't believe this is related to Vista specifically but we think this may be related to Ultra Mobile PCs (UMPCs). Intel recently announced that it was gearing up to a release "before April" of the much hyped mini PCs that include WWAN and GPS capabilities. Intel's UMPCs are likely to be similar to the OQO computer released last year.
Intel expects a wave of new UMPCs to be released in the second half of 2006 from LGE, Acer and Averatec to name but a few. These devices will be running on Windows Vista. Microsoft has a habit of creating odd sites weeks before a major announcement to do with new hardware with Vista capabilities. The company did the same last year when it was ready to announce a design competition for Windows Vista PCs at startsomethingpc.com.
