The marketing for Android tablets is such that most people associate it with sub-$100 7-inch screens with awful quality, suitable only for keeping a 5-year old entertained.

That's actually not all that off-base. Aside from Samsung and Huawei, I don't think there are any recognized companies even building large, high-res Android tabs with Pen support. And even Samsung seems to be doing it ceremonially to compete with the Surface Pro and iPad Pro, both of which I'd guess sell far better than the Galaxy S3 tablet.

Even so, I doubt there would have been a movement towards using Android tabs as full laptop replacements. I'm an Android user and at no point did I think I wanted to use it for work; I got a Surface Pro, which is much more suited to that task.
