That isn't the mistake, it's making a tablet OS for desktops.
And who knows, they said Windows 8 was going to be 64 bit only, then decided 32 bit for ARM only, then 32 bit for all. So they may continue to do that again and again.
Its not a tablet Os I think this has been coverd
Microsoft never said this that was the rumor but then MS debunked them.
