Good luck to M$. I really don't think they understand the market place. Poor sales, IMHO, are being driven by the fact that businesses will not spend the money on it after finally having spent a considerable amount of money to upgrade to 7. Maybe doz 9 or 10 will be the next best seller.
The issue isn't with their push to create a new style of computing across devices, but more of the poor execution on the desktop front. The metro-slapped-onto-desktop approach was a bad idea, and I feel like their innovation was just half assed. They created a start menu replacement that lacked any benefits for a parallel workspace, so they just left in the traditional windows desktop.
Windows 8 really has a lot going for it. So I think Microsoft would be wise to give consumers the choice of UI, while still allowing access to the Metro UI if they want to run marketplace apps. More choice and letting the customer tailor the system to their need/wants is not a bad thing.
"Many people may disagree, but one of Microsoft's biggest mistakes with Windows 8 is forcing desktop and laptop customers to boot straight into the new Modern UI overlay."
Who disagrees? Practically everyone is saying that Metro, while not inherently bad, should be optional, particularly for desktop users. If I'm not mistaken the feedback they got during testing noted this too, so they shouldn't be surprised at the outcome.
Why can't we have both at the same time?? Why can't Metro sit INSIDE my desktop as an active background? That's what Metro seems to be anyway, is a bunch of active widgets. It seems like this should not be difficult to make happen. Best of both worlds. Metro for those who like it, but same old desktop for people who don't.
If they are kind enough to give you a choice, this is golden. I don't want this through an obscure registry mod; don't be embarrassed to give me the option. Apple "knows" what its users want, MS gives you the choice. If you take away that choice, you are not much different - and PC sales will reflect it.
