yes Raspberry pi is a nifty little gadget but it doesnt sell nor ship everywhere.
A hobbyist board for the tech savvy customer.
Anyways it doesn't quite have the horsepower for thrifty and powerfull apps

That's quite like science fiction like in the matrix where you change the environment by loading a different programs...and by my understanding anything less than a dual/quad-core smartphone/phablet is pretty pathetic as every bit of hardware power counts.

Maybe 5-6 years from now when the word internet is "dead" and cloud is the correct definition. Today you can share data between devices that can connect to a network, tomorrow you might be able to share hardware and computational resources if your currently used device lacks power--much like a quasi home-grid--and shuttling hardware resources irrespective of arch used or OS used.
Moving your /home...........its practically in a different league altogether. Might entail an advanced OS running a centralised virtual pool whose attributes and characteristics get shared at the users request-- much like skynet in Terminator.....wherein a single computer is useless....But in the linux world this is a thing of the past assuming all your computers are running them and are on the same network. Once you bring in a new device like android, windies, Mac etc ..its a dead end.
The biggest mistake of all .. that sd card only chugs along....reliable but you'd need something much blazing for read/write.
i am still wondering whether ARM would do an Intel or AMD by allowing you to build your own system from scratch.
