I use a laptop, but I use my laptop at my desk for most (if not all) of my work day. If a laptop battery stays plugged in all the time, never letting the battery discharge, the battery doesn't hold much of a charge after about a year.
So when I'm at work, I sometimes like to let the laptop run on battery power, and will unplug the laptop from the wall.
Occasionally, I'd forget I'd done this, and would come back from a meeting to find my Linux laptop had automatically shut down when the battery reached a critical level. The default in Linux (Fedora) was to shut down. Plugged in the laptop, booted up, and Firefox restored all previous tabs and sessions, and OpenOffice automatically recovered any open documents.
This happened again the other day with my Windows laptop. I came back from a meeting, and realized my laptop was off. Except it wasn't - it was in standby mode. Plugged in the laptop, hit the power - and the laptop woke up. No browser sessions to restart, no Office documents to worry about.
So I guess that's one thing where the default on Windows makes more sense than the default on Linux. I'll give it that.
