Agree. Setup should be as easy as entering your domain credentials or choosing DynDNS name. Set password and all your basic services (email, PIM, cloud storage, blog, photogalleries) should be activated automatically. None of those need even power of Raspberry Pi. Should run on old Android phone with 256MB RAM and 8-16GB memory card (or as much as you can afford for storage). Hmm... it should be as easy as "What to do with your old Android phone? Download this app, enter credentials, put it on eternal charging, and enjoy".
