Linux is a popular choice for netbooks, where battery life is paramount.
You mean "was", until Microsoft decided to keep Windows XP alive in the North American market for a few more years at bargain-basement prices per copy.

Really? A decade? That's sub-1Ghz. That's two years prior to the release of Windows XP. What modern software are you going to run on a machine that old? At least DirectX was out then, so there exists some software from that era that will run on modern computers (although likely not Vista).
My favorite "useless feature" is track changes in Word. Do you have any idea how surprised people get when they send me a Word document and I send them back all my edits with cute little bubble comments next them? Does OO support track changes? Cause if they dont, that is a shame... it is a damn useful feature once somebody drops change-tracked document on your lap and you go "wow, I never knew this existed!". But I can only imagine the number of 37-signals followers who sit around and call it "useless bloat!!! off with its head!!"
OpenOffice does have track changes, under a slightly different name:
Edit -> Changes -> Record
Suggest you just sit there and wait till life gets easier.
