First I would like to have a phone with x86 cpu so I could run the same software as on my desktop, without real desktop cpu it will be hard to use device like that as laptop replacement.
Secondly why would I like to carry something like that instead of normal laptop. I understand I can buy e.g. two devices one for work one for home but still why not just have a two laptops and sync stuff using cloud.
I think it's not a future, the future is folding device that could work as phone and unfolded as laptop. We are not there yet to combine everything in one device that would be useful for every use-case.
