A few of those such as Netflix, won't work outside the US, but it's still a good list.
I'd add one more for Canadian users. The iPad version of the Kindle App is a must because you can use that and iBooks to maximize your choice of titles available to you. Especially since iBooks isn't live yet in Canada. ;-)
Civ Revolution is great! It gives me enough of a fix that I've stopped playing my computer version.
