If you don't need wi-fi and bluetooth in your bat cave, you can turn them off. Some research sites have low light so you can turn down the screen brightness. The keyboard is the same as the P but recessed a little. Are you sure you don't want to use the power cord? If you are researching from open to close constantly using the computer the battery won't last. You have to work within your computer limitations and the battery is just not designed for that. Buy a spare.

I actually like the battery bulge as a practical matter. The cooling is easier when the back end is raised a little and the typing is easier than with the computer flat. My flat MacBook has two plastic erasers under the back end to raise it for cooling and typing. They're cheap and useful at school. Are you sure you don't want to use two batteries?

My family is visiting me right now and one of them has a Sony TT ultra-portable. She says she loves it. I do too. Sony Style.
