We all know just how great Windows 7 is, but Microsoft's OS from yesteryear, Windows XP, has still enjoyed being the OS market share king, until now.

With the latest market share data in hand, Net Applications says that Windows 7 has passed Windows XP completely in OS market share. Windows 7 now enjoys 42.72% of the OS market share pie, leaving XP with 42.52%. We're not talking much, but its enough to claim the #1 spot.

Windows 7 will most likely be the Windows XP to Windows 8 when its released. Windows 8 will be great, but it won't have the same push that 7 did. It will be strong on smart devices, but until the screen tech gets cheaper (bigger screens, higher resolutions, touch compatible), that push won't be there for the end user.
