I have a custom built desktop I use to run Linux/BSD/whatever OS I have on the hard drive this week. I consider that my main machine, holds all my dotfiles, personal stuff, the whole 9 yards. I use it the most.

I also have a 2012 Macbook Pro that now runs OS X. I've always used that as my "set up and forget it" machine in that, I dont tinker with it much. I just want it to work. I usually use it to talk on skype and google documentation when my desktop is FUBAR.

I own a Dell Chromebook 11 that I bring on trips. I use that solely as an ssh client and for chrome. Nothing else really.

Those are my three machines I currently have in use. I have a plan 9 "cluster" that is sort of turning stale, I sadly haven't turned it on in awhile. I'd like to get back to it soon though. But again, I really just use those three machines. I also have an iPhone and a Nexus 7, but I use those in the same way as the Chromebook. SSH/contacting people really.

To keep it all together, i use a messy combo of Google Drive, git, and sometimes rsync. My whole setup is really wonky. I am doing some intense cleaning for college though. I'm getting rid of stuff I don't really need (extra peripherals, monitors, formatting drives, figuring out a use for currently working hardware) so hopefully my setup will make more sense in the future. I'm also considering using some old boxes I have in my closet as servers for a VPN i want to create. That would consist of my Macbook, desktop, and then those machines. I'd probably use that for backups and MPD, to stream my music library to all my devices.

Hopefully I can get that working soon.
