Wondering if either of these e-readers has decent internet access, or is it abbreviated like with cell phone (mobile) Google, etc?

Also, Amazon says their Fire 3G operates all over the world. Is this 3G for downloading books and movies only, or can it also be used for internet access so I can check my email, flight details, read the FT forum, book hotels while traveling, etc.

In other words, will it do almost what my netbook does, except store massive amounts of data and give me the keyboard?

Or does it work as just a big oversized cell phone? In which case I can bring a non-active smartphone with me and just hook into wi-fi wherever I am able.

Heading to Central America for a month in July, will be in Nica, Honduras, and Guate.
