With the Xyboard series of tablets running Google's Honeycomb operating system, and ICS-upgradeable, users will have full access to the Android Market, allowing them to buy all sorts of cool apps, as well as the Google-only applications like Earth and Maps.
Other Internet Features
Though not necessarily an internet feature, the onboard IR blaster, and pre-loaded application to guide it will allow you to use your tablet as a universal remote. We're seeing this a lot on new tablets at CES, so this may be a feature that catches on in the future; or not. It's too early to tell.
