It may be a bit exaggerated, but I had exactly this problem multiple
times already:  Touchpad tap sensitivity is *way* to high and trying to
move the pointer causes unintentional clicks all over the place, even
after figuring it is very sensitive and being extra careful because of
that.

Dunno whenever that is due to crappy hardware or crappy software or
crappy default configuration.  Usually I grab a usb mouse, turn off
tapping, be happy.  Saw this not only Linux, but Windows too.  Also
there are touchpads which work fine.  Which makes me suspect it is just
crappy hardware.

cheers,
