>>I don't think I said anything about phones nor tablets. The numbers Ed Bott referred to broke out ultrabooks separated from PC/Laptop and show ultrabook sales increasing at a higher rate than laptop/PCs were declining.

He was rebutting the claim that Windows is dead, which is based on Windows numbers compared to other devices. His claim is that adding ultrabooks to PC turns the tables- but he seems to ignore market share.

Example: here's the figures that he's relying on and published in his article. These are shipments in 1000s of units:

For 2012:
341,263 PC (including notebook)
9,822 Ultramobile
116,113 Tablet
1,746,176 phone

And for 2017:
271,612 PC
96,350 Ultramobile
467,951 Tablet
2,128,871 phone

His argument is that the shrinking PC numbers are what caused the prediction of doom but if you add PC and ultrabook, 2017 is more than 2012, hoorah. But look at the total numbers! Tablet has overtaken PC that shrinks from 16% to 12% of market even if you add ultrabook. Phone and tablet is where it's at- and when you look at OS market share in those, MS is in trouble. It's clinging on only in the shrinking PC market even if you accept Bott's assumption that all ultrabooks will be Windows.
