Huh. 2010 blurb but no evidence that promised drivers have been
forthcoming.  It isn't clear to me that the terminally cute visual
gesture tricks could be enabled without extensive accommodation from X

Conventional touchpad support. (Well, the "clickpad" feature requires
slightly more than "basic" to disambiguate click from touch.)  I don't
much care for touchpads in the first place.  But it's a tad annoying
to be *obliged* to plug in a USB mouse, something I might *choose* to do
more often than not.  The multitouch/gesture stuff is stuff I'd be at
pains to turn *off* if I had it. (I can imagine it being useful for
projection presentations, not having to fiddle with carefully
positioning a cursor in front of an audience, but not for stuff I'm
likely to do.)
