I think it's been discontinued for a while now.
If by some chance you're on a Mac, get a Magic Trackpad. If you're on Windows 7 or 8, get the Logitech T650 (it feels lovely and solid). For other OSes, I don't really know...
Filcos touchpad works for Mac, Windows and Linux. Ubuntu obviously as well.
"Works" and "works well" are two entirely different things. (Remember, we're Mac users. We have extremely high expectations.) It's vanishingly unlikely that any gestures beyond moving the pointer and scrolling are supported on Mac (and likely Linux). For Windows it would have to have included a driver. And we know Filco doesn't do Mac.
Wow, you think its better than the apple one? Impressive 
IMO Apple makes the best trackpad/firmware out of any laptop manufacturer.
Agreed. I have not used any trackpad that has even come close to being as good as Apple's. And given that a lot of non-Apple touch gear uses the same hardware under the hood (and that Apple's trackpads don't work anywhere near as well under Windows as under Mac, even with drivers installed), it is obvious that the driver quality is
essential -- and that nobody else has gotten it right.
(I feel the same way about mice: it baffles me that Apple-style acceleration curves aren't used more widely in the computer industry.)
