Metro and it's ugliness might make a lot of people decide not to buy Windows 8 in the first place.
Exactly! Microsoft may think it is catering to the app happy now generation, but there's millions of old school PC users who will not be at all impressed with the new format... especially if it is enabled by default. So unless Microsoft provides users the option to select their preferred GUI at setup, because most will have no idea how to change it otherwise, Win 8 could very well be the next ME, Vista in terms of consumer uptake and popularity.
For me it will be all about choice and whether I can do things the way I want... whether or not I will be forced into some registry hack or 3rd party app to access the kind of desktop environment I desire. And no, it's not about being a dinosaur and not moving with the times. You either like something or you don't... and I simply loathe the concept and look of Metro.
I have no wish to put a downer on anybody's enthusiasm regarding the skinning possibilities opened up by Metro's pug fugly ugliness, but as Starkers and I have stated, Windows 8 could have a pretty poor adoption rate. As it stands, I've no reason to buy Windows 8 because I'm perfectly happy with Windows 7. What is 8 going to bring to the table that I and many others are going to feel we just have to have? I don't have a smartphone, and I don't have a tablet. And sure, it may offer a Windows 7 GUI as an option, but I've already got that.
There were many, many PC users who skipped Vista and weren't easily convinced that 7 was worth moving to from XP. Depending on who's figures you look at, the adoption rate from XP to 7 looks great or mediocre. So again, what is Windows 8 going to offer that will compel people to buy it? It certainly isn't the interface.
As I've said, I've no wish to piss on anyone's chips/fries. But how many people in this economy are going to shell out the money for a new OS, and then spend more money on customisation software just so they don't have to deal with it's fugly GUI?
From what I can gather, whether you're skinning a tablet, desktop or smartphone, you're required to have it so you can test the skin as you create it. If you already have these things, great! But if you don't, are you going to buy a tablet just so you can create skins for it? Maybe I'm wrong on this last point. But ultimately, how large a customer base are you going to be skinning for when it comes to the different devices?
