Lol, it's pretty obvious you haven't actually used the Xoom from that pitiful review. The 'built-in' apps are better than any other out. Unless you meant that there needs to be more apps... which of course is true and will correct itself over time. iPad once suffered from this problem too ;-).
But what makes it obvious that your just trolling... there is no tablet out with a higher build quality. Sure, several may match it or come close (most of which are not even available yet)... but it doesn't get any better.
