I do a lot of work outside of an office too, but I don't care about the battery life advantages. For my workloads, battery life is already terrible in a modern MBP, because all those great battery gains from the last 10 years are really about idle performance, not flattening the processor. My MBP is rarely quiet: Too often it has to do enough processing to sound like an airplane about to take off. If you actually tax it, it lasts about two hours before it runs out of juice. I'd much rather have more power and less battery life than to just give up, buy a tablet with a keyboard, since then the computer is nothing more than a modernized VT100 terminal, and do all real computing in the cloud.
