I'm still a student and have to move every week from my home to my place in the city near the university. I have a laptop at home but also a desktop in my other place. I use SD cards to synchronise the files in both places. The same for my music library but I don't synchronise it so often, only when I take my laptop to school.
Besides I'm gonna set up a little server at home to synchronise my docs and music with each week. That way, the entire music collection of everyone in the family is also available for everyone and synchronisations can be used to update each collection. Meanwhile, you also get 4 hard drive back ups in different places at home.
Only problem is finding enough storage room on my laptop
