A Windows forklift upgrade

I've never heard of a service pack SDK, but apparently the changes going on in Windows XP are so intense, Microsoft's going to release the first one, according to Lockergnome. It appears to be another sign that the Windows community is about to be dragged through what I predict will be its most wrenching forklift upgrade ever. (For those of you who've never heard the expression, "forklift upgrade" has often been referred to as the most painful yet mandatory type of software upgrade that IT managers can imagine.) Depending on how effective the upgrade proves to be, relative to the pain of deploying it, this could open the floodgates to Windows competitors from the Linux and Macintosh world. But that remains to be seen.
