Couple of questions of my own...
1. Why in the world you need a touch pad like that in a Laptop when you already have a touch screen. Can't you just touch on the screen instead of clicking on the screen? Touchpad is provided as standard in both Asus Transformer series keyboards and also Microsoft's Touch and Type Covers, which are essentially keyboards which can used as covers (or screen protectors) too.
2. If Windows 8 is really serious about transforming Desktops to Windows 8, they should have at least included touch screen drivers for handful of multi-touch displays available in the market (there are about 6 good ones). Why didn't they.. it is typical Microsoft.
3. Oh.. BTW.. Windows 8 doesn't yet support dual touch screens natively yet. Who on the earth in the right mind would have dual touch screens? I have two DELL ST2220T touch screen monitors.. so just to test I connected them. The result is a very awkwardly behaving desktop computer. When I touch on the second display it thinks that I am touching the first one. I hope Microsoft will release a service pack to fix this.
