Is nothing more than a trackpad that supports multi touch, which hasn't been unique to Apple for years. The only thing that stands the trackpad out against the rest is the software. I absolutely hate having to go back and use Windows laptops because of the trackpad. Not because the trackpad is bad, but because the software is. Even with multi touch and gestures, they don't feel as good as OS X.
If I have to use a Laptop, which is a rare event and which I consider to be a punishment (irrespective of manufacturer) the first thing I do is connect a mouse. I simply hate track pads touch pads etc. wife's the same, she won't even press the start button unless a mouse is available.
