So when will we actually be able to purchase a real product?
Trying not to be a killjoy, but Ubuntu have been working on converged workstation/smartphone for some years now and although we have seen some good demo's, they've all been for R&D purposes and not for sale.
So whilst I can see a niche and use cases for these devices, I'm not holding my breathe or getting excited - perhaps I've just been in the industry for too many decades...
