I like the ~/x and ~/i. I also usually create a ~/tmp for temporary builds and stuff that I don't want to have automatically cleaned up, but about a year ago I changed the default download location in the browsers I use to /tmp -- this has saved me a lot of space and a lot of time cleaning stuff up or trying to remember what something is or why I downloaded it -- the system cleans it up, and if I want to keep it after looking at or evaluating it, the act of moving/copying it out of /tmp is enough of an effort to help me remember more about it.
