Can I just ask why you'd choose this over a used laptop? The only thing I can really think of is that you'd want a specific hardware with very specific specs but also a dev could just choose a much more prolific piece of hardware and do the same.

When you add to that that Google has tried repeatedly to make an android like experience for tablets and laptops and failed (with their line of Chromebooks especially), I just don't know why you'd want that. App stores being what they are and us already relying on app devs to try to support different screen sizes and hardware tiers with different specs, it's been kind of a crapshoot so far. What makes this idea more viable?
