That tutorial is getting a bit aged. While I think it is still pretty
good, students of AltiVec should also be aware of two other things:
Apple's Velocity Engine web page, which covers the same material from a
somewhat more theoretical standpoint, to help you avoid the list of
mistakes that new vector programmers almost invariably make:

Look at the third section in the bar at left, "Writing AltiVec code".
It's not entirely theoretical. There are plenty of practical code
examples for solving common problems.
In addition, Sanjay made a nice hands on tutorial a few months ago
which is more practical than theoretical, covering handy tips and
frequently observed pitfalls.
The two compliment each other pretty nicely and should introduce you to
all the mistakes you are going to make before you make them, provided
of course that you take the time to read both before writing, something
I'm not sure many people have the patience for. AltiVec is fun! ;-)
