Installing Xubuntu 16.04 on USB stick

I'm just curious to see how 16.04 LTS is performing with Xubuntu and i3.
For that, I'm installing it onto an USB drive and run a live distribution with additional space for userfiles.

After that, I'll install i3, copying my default config to it, and then enjoying a portable, effective system. But like I said, it's mainly for testing purposes. If it runs well, I might use it to watch movies and to surf the internet from other PCs.
