I keep seeing this phrase used here by people who don't believe that the user/owner of a computer should have to perform any maintenance, e.g., installing updates and service packs.
You can't just buy a car and drive it around. You have to put gas in it. You have to change the oil every so often, rotate (or replace) the tires, get the alignment checked, replace the brake pads, switch out the windshield wiper blades, change the transmission fluid, etc.
Guess what, folks. Computers are like cars. You have to install necessary upgrades and perform maintenance. It is your responsibility as a car/computer owner to keep on top of this. If you don't, bad things may happen... your car's engine may seize up from lack of oil, or your computer (or, more likely, its software) may fail due to a problem in the code that's resolved by an upgrade or patch. Sure, some OSes are easier to maintain than others. But it's ludicrous to use an outdated version of an OS (in this case, Windows XP SP-1) for a test when Microsoft has been urging EVERYONE to install SP-2.
So please, stop saying "well, it should just work". Yes, I agree that it should, in an ideal world where there aren't miscreants writing viruses, worms, Trojans, spyware, and adware. But for now, everyone, and this includes Windows, Mac, and Linux users, needs to be an active computer user (not a passive one) and keep their machine up-to-date.
