"When the touch aspects of Windows 8 are taken into account, what is needed to make good use of Microsofts operating system is a track pad that recognises multi-fingered swipes and gestures. Youre not going to find that at this moment with Apple hardware."
What? How about Apple's Magic Trackpad? It's been out for quite a while. Available as built into some MacBooks or as a separate piece of hardware. Maybe the problem you are experiencing is that the Win8 system needs drivers to take advantage of how the Magic Trackpad operates.
