Hulu Plus Video just looks so much better on the iPad than on a teeny tiny phone! Hulu Plus does a great job of streaming high-quality video onto the device. (it's invite-only for now, but the turnaround is fairly quick!)

Words With Friends HD Words With Friends is super fun on the iPhone, but that game board is just so much nicer in giant-form.

Pages Document creation on-the-go, when a laptop just isn't accessible, is super easy on the iPad. I certainly wouldn't want to do it on a phone, and Pages is the next best thing to working on my computer.
