When looking at Windows 10, I think it is pretty important to look back over the last three years, because none of this is ever built or designed in a vacuum. Microsoft has a huge number of devices running Windows, but a large majority of them are running Windows 7, which was an evolutionary desktop upgrade. Windows 8 struggled to ever take over any of that usage share. Windows 10 is Microsoft's attempt to bridge the divide. Windows 7 is used by hundreds of millions of people, but its touch support is practically zero. Windows 8 works well in a touch scenario, but is not ideal for keyboard and mouse based devices. Windows 10 promises to be the version of Windows which bridges this gap.
