Microsoft have added an interesting feature to their new Surface Pro, the ability to limit the battery charge to a maximum of 50%.  Now, before you start tossing things, this is specifically for scenarios where the Surface Pro will be plugged into mains power all day long.  Limiting the charge should increase the lifespan of the battery, though woe to the user that forgets to change that setting in the UEFI it before heading out on the road.  As The Register points out, Microsoft have had a spotty past with batteries; hopefully they've learned from their mistakes.

"The setting is only recommended for scenarios where a Surface Pro is constantly connected to a power supply – "all day long" as Microsoft put it, such as in a kiosk situation or perhaps permanently wedged in a desktop dock."
