Always sync 2 macbooks I have a MacBook Pro 13' and recently I received a MAcBook Air 11'. The Air is not big enough for me to use day to day but it can be helpful when I'm out of home.

What I'm wondering is 2 things:


What uses can 2 macbooks have?
How do you keep them sync so when I use the Air, everything from the Pro is there?


Thanks
The Air will make a great machine to throw in a bag and just get out of the house for a bit. 

Depending on how much you need to keep in sync the way I prefer is to use Dropbox with symlinks to the relevant areas, lets me keep stuff like my Coda sites in check across my machines.
