I have a nearly ten year old XP based computer that I use as a dedicated video server. It is networked with all our laptops, and we stream Netflix via a hardwire ATT connection to it, and play downloaded movies on it. It also uploads my weather station data 24/7 (

I've been hearing XP death knells for a long time, and in fact, I haven't seen an XP update on it for a few months now. But, until something takes it down in pain and flames, it does fine.
