I really like the phone/desktop convergence concept. Mostly I think because I want the freedom / open experience of my desktop on my phone though, I think.

But I think most folks interested enough in the concept are also rich enough to afford a phone and a laptop, and if you want a keyboard for your phone you might as well just use a laptop.

I still think conceptually it's the right direction for tech that our devices should be so flexible, but it's hard enough in practice that it's not generally done.
