i'm not exactly surprised about xp losing support either, it's a really old OS at this point and steam supporting it for almost 5 years after microsoft dropped official support for it is something to be commended. still blows for a guy like me because i would run old games on xp machines via steam for the hell of it (and it's an oof right in the nostalgia), but at the same time it totally makes sense for them to drop support.
