Microsoft and Windows 8's problems aren't the bullshit wrapper you put on it. Well there is a problem with the way they are using marketing to push an ecosystem, but it has nothing to do with a bit of graphic artistry. There are so many reasons not to take the jump into Windows 8, how the hell is clean design supposed to make any real difference. There is a tiny subset of customers that are absolutely clueless about what they are buying when they get a computer, tablet or phone, this kind of design might have a chance of roping them in. All profits at the margin so maybe good design could make a few sheckles but it could never, will never be enough to get the current windows on track. The only reason to enter the Windows 8 ecosystem (I'm lumping RT in here) is if you are buying a new computer. There is no add campaign or logo that can change what the product is and does so that it becomes desirable to well informed consumers.
I agree that there are fundamental problems with Windows in general, however a great marketing campaign and new look and feel can go a long way into making people who have shunned Windows take a second look. Windows is losing customers to Apple products because they are clean and easy and "cool." I'm not talking about Apple fanboys and techy artists types. Moms, Dads, Grandmas, etc. Everyone that buys a new computer these days takes a solid look at Apple products, especially if they already have an iPhone or iPad. Windows needs to figure out how to keep their current customers, not only get new ones. And a hip, cool, simple repackaging is a step in that direction.
