Another point: Android is "free" for the carriers and manufacturers.
That's a big difference.

Its not Apple vs MS/Nokia vs Samsung+Motorola+.... as you are claiming. There are myriad of other manufacturers who are making Win8 devices both phone and PCs/tablets.
Also android being free is a myth. It just cost Samsung a billion for making android phone (somewhat indirectly though) also MS has been after a bunch of the android makers for license fees. So what makes it free?
Somewhat? It being Android really had nothing do with what happened to Samsung.
Uhm, yeah.. That's... puhhh... Nokia... HTC... probably some HP and Dell? But how much effort will they put into Win8 devices? Nokia is near-death, HTC is focused on Android, even Dell will have more Android devices then Win8 ones (i guess).
Most likely (and this is another point the article doesn't mention) Microsoft will throw some billions and billions of dollars at the problem to gain traction (as did with the Xbox, the Xbox wouldn't have been a success without Microsoft subsidizing every new xbox) and then we will see if it sticks. It can become a second Zune.. or a success. Right now they don't have much on the plus side.
