In less than two years, a smartphone could be your only computer

I think it is possible.

Easily hooking up to large monitors and/or 4K TVs will be important. Also new designs in furniture, where some table and counter surfaces becoming virtual keyboards with nearby displays will help also. My Note 4 is powerful enough for a lot of work with better peripheral support.

They kept saying this for many years now. Depends on who the "your" is. This is not true for anyone whose uses a computer for more than just e-mail and browsing. and smart phone still sucks for the latter.
