So is its notorious tendency to keep developers and consumers within its walled gardens. The 'One Microsoft' goal that looked like more gaseous corporate rhetoric upon its debut last summer now is instead much closer to actual reality. No longer are there different kernels for Windows 8, Windows Phone or Windows RT it's now all just One Windows. As goes the Windows kernel, so goes the entire company. Microsoft finally appears to have aimed all its guns outside the company rather than at internal rivals. Now it needs to rebuild its empire upon this new reality."
