"...there is no good reason not to use 8."
There's a point where such willful blindless is actually effectively deceptive and counterproductive. You're there.
Here are some examples of a fully truthful and precisely accurate statements, just so you'll learn the differrence.
There is no good reason why Microsoft cannot include an alternate Win 7 like GUI that would be a selectable option. That $5 aftermarket Start Menu fix should be bundled and supported by Microsoft.
There is no good reason why Microsoft should take it upon themselves to forcibly bundle a sub-optimal childlike tiled GUI, ideal for 5 year old little girls drawing happy faces for daddy, with other valuable and necessary OS improvements.
There is no good reason why Microsoft should literally withdraw Win 7 FPP (Retail) from the marketplace to force people to change.
They have made bad, stupid, decisions for seemingly GUI-religious reasons.
"Convert or die" is simply pure evil. There are vastly more evil examples in the world, but Microsoft are still clearly in the wrong.
