In today’s Windows 7 keynote (to watch video click here), Steven Sinofsky presented this slide which shows all the companies currently working on Windows 7 touch products.
N-Trig I hope will have its Windows 7 multi-touch driver available here. The N-Trig digitizer is included in the Dell Latitude Tablet PC–one of the few multi-touch devices available. From what I understand, the N-Trig multi-touch driver will support 10 contact points, which is quite promising. By contrast, the HP Touchsmart displays currently support two touch points at most.
