If you look at the bill of materials for a smartphone, the SoC is like... $20? Making the sort of interconnects you'd need and making them reliable enough probably costs about that much. For most people this need can be solved with software (Dropbox/OneDrive/iCloud), not hardware.
Maybe I just had a bad experience, but keeping multiple machines synced, particularly in terms of software configuration and options. Getting the various tools of a toolchain together once often sucks, doing it several times each time you make a tweak sucks extra.
Also, these sync services sound great, until you're losing data due to bad sync. I tried to use Google Drive for this and lost data. So, I'd rather have one machine, well backed-up.
You're comparing the real-world implementation of something to a hypothetical. I bet that hot-swapping base machines into different form-factors like that will be just as ridden with technical problems as cloud storage is.
