That's a nice link to some Office-like document editing tools available now on the iPhone.

When you travel, you have a choice (in theory) of what type of computer to bring/use:

• Smart Phone
• Netbook (about $350 - $450)
• Traditional Laptop

There are obvious trade-offs in price, weight, power needs, ease of use, screen size, etc. On an airplane, if you need to deal with email, Office documents and want web access (assuming WiFi is available), a netbook might be a nice compromise.
