Yes, although I like the iPad Mini, the screen size is too small for me, So I would like a 9.7 inch display with the same thickness as the Mini. I like watch videos and movies on my iPad, so I prefer a larger display. Personal preference.

if Apple could make the regular iPad as thin and light as the Mini, sure. probably won't happen till iPad 8 or 9 though
