For a while. Mine doesn't any more, and support services were shut down shortly after the acquisition.
You might think a keyboard with no moving parts would work basically forever, but there was apparently a problem with certain driver chips in the keyboard's circuitry. Some members of the FingerWorks Forum isolated the problem, and had posted a how-to for people to replace the chips (easy as pie if you're comfortable with surface-mount rework) -- but Apple eventually took down the forum, and with it, that information. I hope it's still available elsewhere on the Web; for various reasons, I haven't looked.
There was one other issue -- the software FingerWorks provided to configure and customize the keyboard turned out to be incompatible with newer versions of Windows and OS X. We found workarounds, but again, they were documented on the Forum, which went away.
Of course, none of this would have been any better if FingerWorks had simply gone bankrupt and shut down.
