I used to have one like yours. All set up with many environments zipped up & ready to extract. I vaguely remember writing batch scripts (yukk) to automate 7-zip

I used to have one like yours. All set up with many environments zipped up & ready to extract. I vaguely remember writing batch scripts (yukk) to automate 7-zip's encryption for a locked up computer that didn't allow truecrypt. In the end it just wasn't worth it. However long I worked on it, it just didn't compare to having my own laptop. These days I just use my USB drive for transferring documents.
