XP needs to die. It's a walking security trap. MS ending support for XP is just as important as them ending support for IE6. Frankly I wish Chrome and Mozilla would also stop support on XP.
Google and Mozilla are committed to security. Microsoft is too, and that is why they postponed the ending of support. It will be a chaotic world if Microsoft stops releasing security fixes to XP when it still has a big market share and allows malwares, botnets, etc. to be installed and propagated easily.
