After delays and rumors, the Windows XP era has finally reached its end. Microsoft has made it official: Monday, June 30 will be the last day Microsoft sells XP to the masses. In fact, some companies have already stopped offering XP as an option on new machines as they prep for the switchover.

There were early rumors that Microsoft might extend the sales date, but that rumor died as well. Microsoft has reiterated that, indeed, June 30 will be the final sales date cut-off for the product. It’s all Vista now or at least for Windows Operating Systems.

There will still be copies of XP floating around for some PC makers for a short while, namely those who are building ultra-low-cost computers that aren’t powerful enough for Vista.

XP fans needn’t panic about the loss of XP. Even if you don’t have a copy on hand, the product will be available through many channels for years to come. The distribution channels will be from retail outlets and the aftermarket. If you search eBay, there are nearly 1,000 copies of XP available for sale, and they usually sell for less than $100.

The other good news is that even though new copies of XP will no longer be distributed for sale by Microsoft, they will still support XP until 2014.
