Highly anticipated, my only question is, why did it took so long?
Windows XP (and Office 2003) is going into reduced support. It just means maintenance to it is no longer free, but security bug fixes are still free. Having older version of Windows moving into reduced support phase is a routine matter by now and is usually noted as such. Not this one. Unlike moving previous Windows edition to support, this one generate a lot of anxiety because Windows Vista is quite frankly, not up to scratch.
It will now be interesting to see whether the “reduced support” phase might be extended. Only time will tell. This is still not a sure thing as it will depends on Windows 7 performance in the market. If it does not do well, then Microsoft will want to hold on to existing Windows XP customers rather than pushing them to upgrade for the fear of alienating them.
