To be honest... If tomorrow WINE was 100% perfect, we'd probably see laptops start moving the direction of phones and it would be terrible for consumers. You'd get your AceOS on your Acer laptop and DellSys on your Dell and so on and they'd all have little marketplaces where you could install LibreOffice next to an ad for some other office suite that costs $100 for some reason and that's all people would know.

Yes, techy people would have more options but for the average consumer, they have no idea what an OS is. Many don't know what Windows is. They don't care or want to care. If presented with the average Linux install screen, supposing they could make it that far by figuring out how to make a bootable flash drive, they'd freak out at all the options and information presented. They're at the mercy of the manufacturer, and the manufacturer will want to squeeze out every last dollar, and being given control over the OS would be terrible.
