Take a look at the latest marketing video for the HP Slate, the tablet computer that should be launching fairly soon from HP. As you can see in the video, it appears that HP has built a program that runs in Windows 7 to give a custom tablet appearance, but when all is said and done, this is really just a touchscreen tablet running a full version of Windows 7, not a mobile operating system. Some will, of course, see that as a plus.
