You are acting like in 2014 XP will suddenly stop working. I still run Windows 2000 on a file server at home and it works fine. Better than XP in some ways, and far better than Vista/Windows 7 could.
If all goes to plan, I retire in 2019.
By then, I hope Microsoft has something I would consider suitable to replace XP. I have no problem replacing an operating system when something better comes along. Vista, nor Windows 7 does not fit that criteria. Vista/Windows 7 still offers nothing I cannot get with XP for what I use it for. They both still have the same thread management bugs that XP has.
Then again, when I retire, I really will not have a need for a Microsoft OS. That will be a happy day.
