said by dib22:The "sprout" ui/software driver/addon is required to make this sort of thing work... as windows 8.1 has no concept of this "input setup" so you will always have to live with HP maintained software on your machine.
Cautionary tale: they did something similar back in the Windows 7 days with their touch screen desktops -- they provided the TouchSmart software which was updated regularly though later versions would only run (or install easily) on newer hardware. And then when Windows 8 came out, they abandoned their own touch software, which was a shame because it was a lot more "fun" than MS's
I've had a preference for HP hardware for a long time now (nearly 10 years) but I can live with their business approach which is they actively support their hardware and any accompanying software for about 2 years and then the customer is pretty much on their own. But having said that, it's likely that my next all-in-one desktop will be an iMac...
