Laptops with the Longest Battery Life?

Yi Ding asks: "Recently, I have been investigating laptops for clients, and the majority of the complaints about current laptops is battery life. Most laptops just don't have enough juice to even finish a single DVD or write an article for 4-5 hours in an internet cafe. Of course, one can lug around extra battery packs, but it's a pain and often defeats the purpose of having a laptop in the first place, portability. What have your experiences with battery life been and where can I find the longest lasting, reasonably robust, laptop?"

A better question...

A better question would be, "What laptop has the least expensive replacement battery?" I'm faced with a trip up the Pan-American Highway to Vancouver to pick up some affordable replacements for my Dell Inspiron 3000, since the existing battery has been a paperweight for a couple weeks now.

Anybody have any idea how incredibly hard it is to find a good outside location in the shade with both a Personal Telco node and a working electrical outlet? I have no idea how Pioneer Square hosts so many events when out of two dozen outlets I found, only one works, and it's located on the roof of the TriMet bunker on the side of the podium that overlooks the square, which also happens to double as a public restroom for the Californian rejects who end up homeless here.
