Don't fret, that feeling you've just been overcome with is nothing more than a harmless dose of déjà vu. Nearly a year ago to the day, we were hearing these same types of talks, and while the whole "XP on XO" conversation has been one of on-again / off-again nature, the switch has apparently been flipped to "go" once more. According to The Wall Street Journal, Microsoft is slated to test out Windows XP on OLPC XO laptops starting next month in the US, India and possibly Romania. James Utzschneider, general manager of Microsoft's Unlimited Potential Group, noted that it "wanted Windows to run on the XO and [that it was] investing significant energy and talent" to make sure it happened. Granted, Microsoft will have to be mighty pleased with the results before any of this goes commercial, as Mr. Utzschneider concluded by stating that the company "wants to [ensure] a quality experience before [making a] commitment to governments."
