First, I would not expect Microsoft to port their Mac Office suite to the iPad, but I suppose it's possible no matter how remote the chance. That said, though, I do expect DataViz to re-write DTG for the iPad, and iWork on the iPad will edit Microsoft Office files. So having your Office files on the iPad so you can work on them when away from your desk is a reality.
One thing to consider is the idea that the iPad is not finished, and will only be finished when iPhone OS 4 is announced. The speculation is that Apple didn't show off the full features of the iPad because they weren't prepared to discuss OS 4. We'll find out in a few months if this is accurate or not.

"Wow" is now overused. Therefore, I will use "Magic bananas" instead.
