Windows 3.1 was a big improvement over Windows 3.0 A friend of mine worked for Intel, BEFORE the PC came out. He's been a consultant since then.
He recently switched his focus entirely to Apple. Said he was finally convinced things simply didn't need to be as complex and troublesome as MS insists on making them.
If they blow Win 10, I think consumers will start to look elsewhere, in bigger and bigger numbers.
I say that because unlike 10 years ago, most of them have seen the simplicity of Android and iPhones.
They know simplicity is possible, and that it works just as well.
So Windows 10 needs to scream loudly and clearly to customers: "We can make things simple for you, too."
