Another interesting thing to note; I noticed someone posting exactly the
same question in Windows Vista Team Blog, but no one seems to be able to
answer it:
The most common reason for this behavior is that you are unconsciously
hitting the touchpad as you type. Many laptops have a button above the
touchpad (or FN + [some key] keypress combination) to disable the touchpad
for exactly this reason. Read the manual for your brand-new laptop to see
how to do this.
