Do any laptops other than Macbooks have multi-touch?

Question

In particular, how well does the multi-touch work (ie. is it laggy or inaccurate) and how many gestures are supported?

Answer 1

Most laptops have Synaptics touchpads, which have had multitouch for a few years now (two finger I think), and gestures for many more years than that.

Answer 2

Apart from the support in the touchpad, there's also the integration with the OS to be considered. Like: scrolling on a Mac never needs you to first click in the part of the window you want to scroll. (The part to be scrolled does not need focus; KatMouse can solve that, for what I've heard. I guess good drivers can achieve the same.)

Also, on a Mac, drag operations allow you to shortly remove your fingers from the touchpad without ending the drag operation yet. So, when you hit the border of the touchpad, you can put your fingers on the other side of the touchpad and continue dragging from there. (Again, I guess good drivers can support that too.)

Answer 3

Laggy: no Inaccurate: no These answers are based on my experience. I have never had a problem with multi-touch, ever.

Any computer can have an Apple multi-touch as Apple sells the touch pad (no Apple's is not integrated into any other laptops I'm aware of). There are windows drivers available for it (Win7 is multi-touch capable on my MBP) For a break down of the gestures go here.
